MiHec .223 boolit loads?

[cricco]

I just casted my first batch from the 62 grain .223 mould. They look perfect, and drop at .226. I ordered a .225 sizer die and top punch. Just wondering if anyone has found a suitable load for these with Ramshot TAC? I'm going to shoot them with an AR 15 carbine with 1/9 twist.

[monkeywrench]

I got in a group buy for one of these. It was started last March. Hope it moves soon. Sounds like a great mold. Don't know about a load though.

Sweet MiHec goodness!

[Screwbolts]

I use a .2265 sizer for said boolitz, I got in on the first group buy for this mold and have cast over 15k of them. I load them at 21.5 of my lots of WC844 for 16" uppers 1x9s, and 22.5 of same powder for one of my rifle length uppers that has a heavy BC. 21.5 works great in my 223 bolt gun also. 21.5 + 2350 FPS in my 16" anb 2530 in 20' barrels. WD , WWs

No ramshot info for me either but my best groups are with Benchmark at just over 2300fps.

[GlocksareGood]

Where did you get that sizer made? I would like to have a couple made for my 4500. Lyman only makes a .225 that i have seen.

I believe there is 3 sources of custom sizer right her as members of this forum. Lathsmith, Buckshot, and the TheProfesser when he regains health.

My H&I die started life as a store bought lyman .225, from evilbay, it only takes a little time to hone it out to .2265. my first Mihec 65gr Nato mold drops at .2265 with my WW alloy so no need to have a larger sizer for it. My .2265 $tar die came from lathsmith .

I just spoke with a tech at Ramshot. He gave me a starting load of 22.5 grains of Ramshot Tac.

I've not shot any cast boolits yet in my bolt .223, but i use 24gr of Ramshot TAC for my j-word bullets in 55 gr and love it. (I started with 26 gr but tamed it to 24 gr and get better groups. I think you are good to start there (22.5) and see what happens. What are you using for gas checks?

cricco:
All the tech on the phone did was to give you the listed start load for a 62 grain bullet right out of the Ramshot load data book.
" TAC 62 BRG HP 22.0 2,775. "

There's that whole SEE thing but I'd not get to nervous about it. I think you'll be coming down from that charge weight to get velocity down. One of my old Lyman books has WW748 ball powder starting at 19.8 grains under a 54 grain bullet. Using a CCI 450 primer to light it.

[GabbyM]

btw:
CCI 450 is small rifle magnum. I've found it best to use a magnum primer in 223 when using ball powders. H335 for instance gave me almost 200 fps E.S. with full power 50 grain J bullet loads when using Federal 205M primers. AA2200 didn't do much better. Rem 7 1/2 is a fairly hot SR primer and was designed by Remington for IIRC the 222. Rem 6 1/2 is less brilliant and designed decades earlier for the 218 Bee and 22 Hornet size cases. I've not tried the Rem 7 1/2 with ball powder but many use it with success. I use the Fed 205M in 223 with the fast stick powders like 4198 then all the way to Varget. The ball powder is probably easier to light when packed less dense. "Room to burn" is what I've heard. I'd still want to use a hot primer. Rem 7 1/2 or a magnum. It's a hard nut to crack because the manufactures do not rate there primers for heat or burn duration.

try 21.5 gr Ramshot TAC, I get 2400fps w/ my 62 gr powder coated boolits. decent enough groups to 75m. full function out of a piston ar

Thanks!

You're welcome, good luck.
H4895 works well too but I am saving that stuff for my bigger bore youth loads!
Report back after you try it!

[3006mv]

Any luck with your ramshot tac loads? I got my info from the company also after noticing and inquiring that the H4895 is next to the TAC on the burn rate charts

[cricco]

I have them loaded, but I'm in New England and it's freezing cold here. Just waiting for a warm day.

[3006mv]

aaah must be a noreastah, gonna get blown out to sea

well i think they should work well for you. i powder coated mine.

I'm in on the 4th run on this mold, and got it for my AR and will probably be a few months before I get to cast any.
So, I probably gunna guess these won't chamber or stabilize in a Remington 700 action with a 1-12" twist correct?

[Screwbolts]

69papa, nope

[69papatango]

69papa, nope
ok, thanks for the reply...I will have to keep my eyes open for one.....any suggestions?

I have a Mini Mark X in 223 with a 1x12 barrel and built one of my Armalite Rifles with a 20" Wilson 1x12, 5.56 barrel. I have one of the 4 cav first group by molds for the Nato boolit. ( well over 15,000 cast from it, supplied several friends with 8000 ready to load ) They cast of my WW alloy ready to load at 62 gr. They shoot great in booth rifles with same load as listed above, simple green lube. I have a six cavity coming in the 4th buy. :-) The loads listed above "werks fer me" just fine.

Size them as large as chambering will allow, I water drop them. I chamfer the necks with a Gracey case trimer. I do not bell necks even with .265 sized boolits.

It seems like most people try to stay around 2300 fps. I've always been told to keep most rifle loads under 2100 fps to minimize leading. I'm very new to casting/reloading and just got a 55 gr .225 Lee mold. I'm a little nervous about where to start. At what speeds (roughly) am I going to get accuracy without building to hot of a round?

[Screwbolts]

Soap, your rifle will tell you.

Hey All...

I just found this thread, and glad I did... I don't have this mold, but have a HMM in 62 grains that I size in a .226 die (a little spring back, and they're .2265)... This is a gas check design; I've powder coated some, and I've used polymer (Hi-Tek) on some... I shoot a pattern at 25 yds, not a group... BUT, I haven't actually put a gas check on them...

The photo of the green PC'd boolits in this thread are a little fuzzy; I can't tell if this is a plain base design or not... if so, I may only need to use a GC to get a "group" instead of a "pattern"... for you powder coaters, do you treat your loads any differently for these boolits??? One post said to use coww, water dropped... that'll make a hard boolit; does the heat of powder coating soften your boolit again?? I'm pretty sure that curing a polymer coating at 375 degrees is lowering BHN. Low-temp powder cures at 250 - 300 degrees.... can't remember if that's true for the Harbor Freight powder, or if it's a high temp powder (450 degrees) which would surely soften the boolits... And do you guys get a smokey trail out of your barrels from a PC'd boolit??? I did, but I don't recall anyone talking about that from their AR's...

Thanks for all the info!!!

From my understanding, if you bake a little longer at 400 degrees, like 45 minutes, then water drop you will regain the hardness.

If you size them properly they will chamber in you 700. I have also shot this boolit in two 1-12" twist rifles and one 1-14" twist rifle and all three were show no sign of lack of stablization. It is also a very accurate design, if you do your part.

Do not bake too long your tiny boolits will warp and melt
