OK, I've got a pile of boolits in #2 alloy cast and plan to size them to .224 with Hornady gas checks. They're running about 61.2 g with check, no lube. None of my manuals have any data I'm real comfortable with for starting loads. I don't normally use j bullet data for cast. I'm thinking about 2000 to 2100 fps and have W748, H4895, IMR4895 and Reloader15 on hand. At least one of those ought to work. Plan to load them for a 16" carbine with a 1/7 twist and 5.56 chamber and if they work in that, possibly a 28" Space Gun, 1/7 with a Wylde chamber. Any Ideas? Places to look? These are awesome looking by the way. Another home run for Miha!

This will be a good topic. Don't have my mold yet though. I think I'll wait till Pat gets back up and running to get a check maker from him. I just have a thing about purchasing gas checks when I can make my own. Sent him an email but just got a form letter back saying he was moving.

I was thinking about mixing up some #2 for this also.

I know someone posted about making a 1.5 inch group with a 1:9 barrel but I cannot remember the data. I think that may be a good place to start.

Use the starting loads for jacketed data to begin with. Hard boolits will probably help with that data.

L1a1Rocker, I'm interested in check making too, but decided to torture test this bullet before investing any more in .22 PBs to make sure they are accurate enough for my use. The Hornady GCs snap right on if you get them lined up right, which I have to do under strong light with my best cheaters. It's amazing how many little flaws you see in PBs when you really look at them close. I never worried about it with handgun bullets, but with a 62 grain boolit at high rotation, I have a feeling they may make a difference. Trying to cull out my best for testing.

Well I took out the boolits I loaded this weekend. I was playing it safe with a load of 8 grains of Unique. Not happy that it wouldn't flow through my dillon powder die, so I had to load each cartridge by hand using my Lyman 1200 DPS 3.

At about 160 yards, the drop was about 14 inches. This was also not able to cycle the action on my RR AR. After about 4 rounds, I shot the remaining 46 rounds out of a Savage bolt action.

Very consistant shots, just not enough power to use in the AR, or have enough power to make it out far enough to land shots on prairie dogs.

I was wondering if I used the loads I use on jacketed rounds would work. I normally shoot 24 grains of H335 behind a 62 jacketed round. Very accurate, and no problems cycling the AR.

Any Thoughts??

Thanks!

A good load range to try is 23.5 gr. to 24.2 gr. of Reloader 22 in front of a CCI small rifle magnum primer. A bit dirty, but we are working on several things with this design.

I took Doc Highwall's advice and picked up the Lyman Cast Bullet #4 book. I had never seen that one and it's going to be really handy. I recommend it if you don't have it. Couldn't find it locally so had to Amazon.

Moonie's data worked like a charm. Point of aim was same out of my 1:8 twist 20 inch bull barrel RR AR as with 55 grain ball ammo. The only thing that sucks is I can't get the 4895 to meter through my Dillon powder measure. No big deal, I just weight each one.
No pics of target as I was hitting a 6 inch steel gong at 160 yards.

That's what I'm using and it kept getting stuck. Have you done anything to your powder funnel to make the opening bigger? I just went an ordered a powder funnel kit that uses the same powder dies. I weigh each load with a Lyman auto powder measurer. Accurate, yes. Quick, no.......

Larry Gibson

I'm using the standard Dillon powder funnel that comes for the .308W. Make sure the funel part is clean and polished. Also, what powder bar do you use? A smaller one dumps the powder into the funnel slower than the large bar.

Most of my venison steaks were indeed "seasoned" (as in shot in season) with 4895. Not necessarily "H" as I use a lot of milsurp 4895 also along with a lot of IMR4895 in the past:bigsmyl2:



4895 is probably the most versitile medium burning powder for use with cast bullets in most all standard rifle cartridges. H4895 just happens to be the best of the 4895s for various well known reasons. If it ain't broke and works, why fix it?

Mihec - 22 Nato

The week before Christmas I made it to the range to shoot some boolits…
cast from air cooled 92-6-2 alloy, sized .225, with gator checks from Blammer.

Shot in a .223 TC 16" contender carbine (1:12 twist) 1½-4½x steel tube Weaver

I started with
LC brass; WSP primers, 7½ grains Blue Dot, 2.260 oal

LC brass; WSP primers, 8 grains Blue Dot, 2.260 oal

LC brass; WSP primers, 9 grains Blue Dot, 2.260 oal

All of which shoot into < ¾" at 50 yards

R-P brass; RP 7½ primers, 24 grains IMR 4007, 2.260 oal opened up to a 1¼" group again at 50 yards.

The 22 Nato seated to 2.260 oal will chamber alright in this barrel, but cannot be extracted without leaving the boolit in the barrel

I had thought that I already posted this but, couldn’t find it so...


Winchester M70 Heavy Varmint .223 (1:10 twist) 6-24x Bushnell

LC brass; RP 7½ primers, 23.2 grains IMR 4007 SSC, 2.240 oal

LC brass; RP 7½ primers, 23.2 grains IMR 4007 SSC, 2.260 oal

The 22 Nato seated to 2.260 oal will chamber and extract without leaving the boolit in this barrel.


Seated to 2.260 oal, groups into about 1½" at 100 yards for a 10 shot group.

the loads seated to 2.240 oal grouped into about 2½+" at 100 yards for 10 shots.

Alloy was 92-6-2 air cooled, gator checks and Apache Blue lube .225 ready to load weight is 62 grains

After a SNAFU on gas check purchase I got around to lube and sizing some droppings from the "NATO" mold. I used pure lino for the alloy. The sizer die had an issue (another story) but I did come up with about 35 good boolits to try. I did loads using Tula 5.56 primers, LC brass and three charges of H4895. The test tool is a S&W M&P 15 carbine. Range for this initial test was 50 yards.

17 grains H4895: 5 loaded --Would not reliably cycle and poor accuracy

18 grains H4895: All (only 5 loaded) cycled ok but last did not lock back bolt. Accuracy was still not good with 3" group of 5.

19 grains H4895: I had loaded 10 of these. Cycled fine and last did lock back bolt. Accuracy was promising with 9 of 10 round group contained within a 1" square and the 10th about 1-3/4 high from center of square.

Next time will be at 100 yards and a few more charges of H4895 -- likely 19, 19.5 and 20.

I used Felix lube and there was not a hint of leading.

Probably have a burr on the cavity edge. There is a proper way to remove those and then your bullets will drop right out. I read it some where on the castboolits forum a while back, but I can't remember the details.

Loaded up some more rounds with a bit more propellant than the initial cast outing last week. Shot at 100 yards from bench with scope. I should have stopped after the first 8 rounds, 1/2" inch group!!!!!!

The last two opened the group up to a gnat's whisker more than an inch. Think that was me from being excited over the first 8. I believe this load recipe is a keeper.

BTW, I run lino at 675 degrees under PID control.

01-08-2013, 08:44 PM
I do not know the velocity but would like to. I have a chrono but my range has very poor lighting and my readings are problematic. I will give it a try and if the results are consistent I will report them.

I will get the OAL next time I get down to the shack. I use the Hornady boolit comparator vs. OAL. I'll report both values when I check my notes in the shack. I suspect I could go longer on OAL but with the current results I am inclined to leave it.

Needless to say I really like this mold.

BTW, I am using Tula 5.56 primers and LC brass. The gas checks are annealed Hornady. I lube and size with a star equipped with one of Lathesmith's fine dies sized to 0.225+. I open the case mouth with a Lyman M using the supplied expander plug and use a Lee factory crimp die to close the bell and put on a VERY slight crimp.

PH4570, I don't have any Tula primers so I am going to try your load with CCI 400, and CCI 450 to see if there is a difference between those as far as accuracy. The Tula 5.56 is a magnum primer I assume with a hard cup?

Also want to try H335 for this boolit. I have a few pound of that, and am running low on the h4895 now. Seems 18 grains of that should get me about where you are as far as velocity.I have gotton better accuracy in 223 with h335 vs 4895 with jacketed.

Hi,
Shot some of my MiHec 22 NATO using 19.5 grs. of IMR 4895 and my homemade Glenn Fryxell moly lube. I used straight WW with a little flea market solder added. Action worked perfect and accuracy was good. Hope to play a little and get that better but was just trying to get everything to function. Brass HAS to be resized correctly using a good guage! I had no leading from my DD chrome lined barrel!

Based on Vihtavuoris loading tables:
http://www.lapua.com/en/products/reloading/vihtavuori-reloading-data/relodata/5/44

This load caught my eye:
HPBT Sierra 64,8gr
COAL 2.551"
Powder N135 18.8gr (start load)
Velocity 2333fps

Sounds similar to the Mihec in weight, velocities are near what i want from a cast load. This one is loaded too long but I don't think it's too far fetched to replace the bullet with the mihec, load to 2.26" and maybe cut back to 17 grains as a starting load.

EDIT: I have some N110 in stock right now, I mean to try it as well first. I hope to cast some bullets this weekend. Waiting for calibration equipment and gas checks still.

Go to the group buy section, there is a third run of these going on now, I was in on the first run and have cast of 12k of them so far.

I load 21 to 21.5 gr. of surplus WC844 for right at 2300 out of 16" barrels. I vary the charge for each 8 pounder for this velocity. that gives me 2500+ rounds per 8 pounder. from my 20" uppers I get 2500 FPS same load.

Made up a batch of these bullets for the first time last night. It's a tricky mold but enough heat makes it work just fine. The weight I got from my test alloy was only 60 grains though, I think next time I can up the lead content more.

Been working on some H335 loads this last week. Seems my pistol has a bigger gas port and will cycle down to 18g, but the rifle is liking it up around 22g. From what I have seen you can go up to 24g in a 1/9 twist without the boolit fragmenting. With the H4895 I was getting three shots touching, but cycling was an issue with the rifle at 19.5g. Single shot only with magnum primers. Rain started again this week so it will be a while before I shoot some more H335 loads. From what I have seen so far the groups have been getting smaller with a higher charge of that powder.

Finally got to actually load a few rounds of these bullets and I noticed they can't be seated to 2.260 OAL with my cases anyway (trimmed to 1.750), that means the lube groove is exposed, so I had to shorten the OAL to 2.235". Is this just me?

Anyway using Vihtavuori N110 in 10,11,12,13,14gr I found that only the 14gr one would eject the case. I will load more when I get the missing piece to my lee auto prime. I was quite negatively surprised last night when I found my vaunted back-order had arrived and when Lee talks about their shell holders they mean they got two of the buggers, one for presses and one for the auto prime. Well color me surprised, had to jury rig a setup just so I could load those 5 rounds with varying powder charges.

Edit: It was a fine day for shooting though:

I assembled these rifles with an M16 carrier. I do have a AR15 carrier around, and thought about trying that after I have a chance to get some other things dialed. The H335 loads are working fine at 21.6 grains, and 23.2 grains. The latter had a POI of a jacketed bullet at 100 yards. I would not go above that load, and have only stretched these out to 100 with no problem with the boolit coming apart. Next time I will do a ladder from one charge to the next to see if there is a sweet spot between them, but as it I was able to plink a 6 inch steel plate at 100 yards off hand with no issue. The 23.2 grain load left divots in the AR500 steel with WDWW boolits with 2% tin. To bad I ventilated my chrony[smilie=b:

My 21.5 of WC844 also leaves divot in my AR 500 plates. :-) We regularly shot them to 335 with great accuracy. My 20" is 2500+FPS with 21.5 gr, 16" is 2350 same load. Minute of muskrat at 335 yards. :-)

After trying enough of the H335 I think I will leave it for jacketed. Just could not get it to perform consistently for me. On to H322. Starting with 19.9 grains and running to 20.9 grains to see where it cycles.
If I could get the accuracy of H4895 I will be happy. I ran out a while ago so I am looking through the cabinet trying other things. This would be easier if I didn't need to cycle the action with gas as well.

I received my mihec nato mold last week and warmed up some 50/50 lino/pb to around 650. couldn't produce a single good boolit in at least 10 casts. damned hard to cut the sprue as well. I see that some are heating the pots over 700. is anyone using a hot plate to keep the mold to temperature or will it stay warm enough during casting if the alloy is hotter? I preheated the mold on a hotplate to about 400 before starting to cast. I am really looking forward to better results from this mold, plan on feeding my 20" RR ar a steady diet. also going to try some h4895, but will be watching xacex for results of 322 testing since I have more of that.

05-11-2013, 12:34 AM
imsoooted, your mold is not hot enough. This is the only mold that I do not take a pause with or use a wet piece of denim to cool. It takes 700 F alloy, and my hot plate set to above medium to get started, and then another 5 to 10 casts to get the wrinkles out. Once you get it up to temp keep casting until you are out of lead in your pot.

gmsharps
05-11-2013, 03:03 AM
I agree the mold is not hot enough. The first indicator is the sprue is hard to cut that says it's probably to cold. Casting for small boolits ie 22 cal you can't be casting slow and when the sprue starts getting easy to cut you will probaly see good boolits being produced. Also has the mold been properly cleaned and deburred.

Get a hot plate and using a themometer set it for 300-325 degrees, set your mould on it along with some ingots to pre heat them also. Now when you start to cast you will have to keep a good pace in order to keep the mould hot making the pot empty faster which is why you pre heat some ingots to refill the pot.

I have a themometer in the pot and on my hot plate along with one on the bullet mould from Al at N.O.E. The temperature of the pot is controlled by a PID that I bought from Frozone a member here at Castboolits.

Casting in the 21st century.

05-11-2013, 08:43 AM
mold has been cleaned and heat cycled but I see no burrs. the boolits dropped immediately when the mold was opened. I do have a thermo in the pot, and I use an infra red thermo for the hotplate and mold. sadly, no PID controller yet, as I am using a 10# LEE and do not want to make the investment for this pot, maybe next one. am going to the garage in a few minutes to try this new info, hope to give the good news later today. thanks all.
'soooted

UPDATE upped pot temp to 725 and that solved the boolit issue. got 1 cavity consistently sticking but the boolit comes out well formed. 50/50 lino/pb had a cast weight of 58.6g so I added a little more pb to the mix and am now at 60.6g. a little more pb maybe?

I have casted some of these a few times now and unless the melt is at 700 degrees or warmer the boolets won't fill out well. This is my first brass mould and there is a learning curve, but a fun time.

I loaded my first rounds today to check for AR function. I started out with 21 grains of Varget and the rifle functioned well, I also tried out 22 grains no problem. I won't be able to check for real accuracy until I get around to mounting a scope.

My boolits came out at 60 grains so I went with the starting load according to my Hornady book.

Tried using N110 some more last night, 15 grains this time, it did not cycle the gun (I have a heavier buffer in the gun to counter act the fact it's a 16" carbine gassed gun, that probably makes it more difficult here). With the suppressor on the last round did eject and feed another so it's right on the limit it would seem. Chronograph said 2450fps and no leading in the bore that I could see. Quickload got it's estimate close here when it giuessed 2410fps.

I will need to either try a heavier charge of a lighter buffer. I do use normal ammo in this so I am not sure I want a lighter buffer just now. But later I will get an adjustable gas block so then I guess I can go for the ligther buffer, since cycling the gun with the minimum amount of gas is probably a good thing for it, and leads to higher velocities.

was at the range today with my RR Predator Pursuit 20" barrel 1/8 twist. checked and lubed weight of 62g, over CCI 400 primer and 19.5/20g h4895. 19.5g barely cycled my action(8 out of 10 cycled), but produced a seated 1.5" group @ 50yds. 20g cycled strongly and also produced 1.5" group. absolutely no leading after the two 10 round groups. alloy is approx. 50/50 lino/pb. I am going to load 50 or so at 19.8g and try them for accuracy at 100yds rested. 80% of the people present could not believe it was possible to cast boolits for an AR.

Most of my venison steaks were indeed "seasoned" (as in shot in season) with 4895. Not necessarily "H" as I use a lot of milsurp 4895 also along with a lot of IMR4895 in the past:bigsmyl2:



4895 is probably the most versitile medium burning powder for use with cast bullets in most all standard rifle cartridges. H4895 just happens to be the best of the 4895s for various well known reasons. If it ain't broke and works, why fix it?

Hi Mr. Gibson,

Firstly, I'd like to thank you for the great threads that you have contributed to.
You have helped me out a lot...and have helped many others.
When I read a thread and see that you have added a comment I generally pay close attention to your recommendations.

I, too, am a fan of H4895 and in this particular thread one of the members recommends a load of 19.5gr. of H4895.
I have a batch of these MiHec NATOs and am just about ready to load...would you recommend a dacron filler?


Keep The High Ground,

H322 cycled fine at 19.9 grains with a cci magnum primer. Could go down a bit from that, but I was testing on a gun with a small port. Grouped, but did not have sandbags to try to get a tight group. I was keeping within 2 inches at 50 yards offhand with iron sights. Much better than H335. Went up another grain and the group started to open up.

Well I finally got some proper rifle powder. Vihtavuori N135 looked real nice in simulations in quickload and I was able to follow existing load data for similar weight jacketed bullets. Tried ten rounds loaded with 21 grains today and had perfect feeding, ejection and bolt hold open. The bore looked shiny and unfired when I looked at it afterwards.

Unfortunately I wasn't at a place where I was able to put up a target at a usable rifle distance, so it was just emptying rounds into the berm and checking function. I will chronograph and test for accuracy later. It felt like a mild load compared to factory rounds, the loading ladder goes up to 23 grains so I have room to test more charges still. Have a good feeling about N135.

I have not had much luck with this yet. So far I have tried H4895 with 19.1 and 19.5 grains. The 19.1 was better but still not good. Also, is the preferred sizing to .225 or .224? And what are you using for COL? I cannot find much information about how folks are loading. I am new to loading .223. Almost all my experience is pistol.

Well, h322 did not produce the accuracy the H4895 did, but it was better than the H335. I could hit a 8 inch target at 100 with it consistently, but that was 20.9 grains. I should have stayed lower on the charge.

22gr of Varget has given me my best accuracy so far at 2 inches at 50 yds and 2360 FPS. This is from an 8 twist wylde chamber gun. More testing to come to see if I can improve the accuracy some.

OK an update. 24gr of RL22 has shown to be the most accurate load so far (thanks Bob ;)). I've loaded up some more test rounds to verify as well as tightened up my brass prep a bit to eliminate variables. Velocity has been a bit erratic with this load but again it may be due to not sorting my brass before checking for accuracy so I'll report back after the next range trip.

Sorry for the very late reply, just saw the post. I recommend dacron (polyester) and cut up "batting" purchased in fabric stores or departments into 1/3 - 1/2 gr chunks fr use in the .223/5.56.
