More Awsome results with the 200 Grain #311299

[Dthunter]

Hi guys!
Here is some pics of some shooting to day.
I only shot at 100 and 300 today.

I only had three rounds left of my Varget load to shoot at 300. In hind site, I really wish I had two more rounds to slip in on the gong!
The picture with 3 shots on the gong is 300 yards with the following load:


Winchester Neck Sized (uniformed) Cases

Fed.210Match primers

34.0 Gr. Varget

200 grain #311299, sized to (.310"), Lyman Super Moly lube, Noses have a thin layer of Lee Liquid Allox.

Seated to snugly fit into the rifling.



The other pictures have the pertenant load info written on the target [smilie=w:back stop.

Hope you guys enjoyed the post today!

I am really enjoying this cast Boolet shooting!

Are you using home made checks in that load. I'm going to Try 33,33.5 and 34gr varget with my aluminum checks and Felix lube.

[Dthunter]

Leadchucker:

I am using Hornady gas checks so far.

I just got my check maker tuesday.
I have spent a few evenings forming checks out of various materials.
I have Brass shim stock(0.010",0.015"), Aluminum cladding (0.016") three or four types/ manufacturers. The aluminum that has the bright blue coating forms very well.
The yellow stuff occasionally sparates on my die. So i scrapped that material.
I dont want a ring of aluminum stuck halfway down my barrel! That could cause some ill effects!

The new aluminum sheeting is forming very well as well.
I think this will be my standard gascheck material, PROVIDED, it shoots well.

I think I am going to invest my time this weekend to casting a large volume of #311299, & #311644 boolets.
If I can get a big coffee can of each made up, that will keep me busy for a week or so weight segregating in the evenings. When that is done, I will have a super supply of cheap,accurate boolets! All I will have to do then is come up with quality containers for each weight category. Thats normally 3-4 containers/boolet type/lot.

Keep us posted leadchucker on your results.
I am looking forward to see how you makeout with your new gaschecks!

Have fun and straigh shootin guys!

[Dthunter]

It was a miserable,snowy weekend here in the north.
So I spent it casting a supply of 311299's.
I managed to get about 1200 done in a day and a half (about 8 hours of casting).
I will need to polish out the sprue plate better. It hangs up and wont release the sprue after its cut.
Its a pain in the proverbial!
I polished and adjusted my cutter a little this morning, and it improved noticeably. But I will need to do a little more to ensure proper release of the sprue.

Later guys!
Straight shootin as always!

[excess650]

Polishing the sprue plate should help, but a coating of mold prep might work just as well. Nice groups, and good work!

[OregonCaster]

Hey Dthunter thanks for posting now this gives me some hope.

[Dthunter]

Oregon Castor:

No problem, this is fun stuff to say the least!
Keep plugging at it.

I will post more results soon.
I have been busy casting and weight segregating the last week or so in my free time.
I cast about 1200+ #311299's last week end.
i may get a chance to load and shoot next weekend, "IF" I get my work done. LOL!

Its a labour of love!

[smilie=s: [smilie=w:

[Dthunter]

Did some more shooting last week end, and got some good results, but this weekend I am sicker than a dog! reeeally bad cold.

I have eight different loads planned. I will slowly increase my Varget & IMR4350 powder charges till I have a load performance failure. I have gotten up to 2275fps with Varget so far.
If my IMR can reach in the high 3300's I will be very pleased!

I hollowpointed some of my 311299's &311644's. Accuracy was "o.k." at 200yds, but not great.
I drilled them using the Forster hollow pointing system. The small 1/16" drill is VERY hard to drill a hollow point of any depth with out breaking! It is absolutely imperitive that I clean the drill bit of lead chips frequently to prevent bit breakage.

Talk to you guys soon! straight shootin!

Hi guys!

Spent another morning casting silver boolets downrange! What a wonderful, relaxing way to spend a morning!

Shot my 311299's yesterday with IMR 4350, and IMR4831.

All targets were shot at 200 yards.

-9 degrees Celcius (15.8F)

Sunny, and very little wind present.

Remington 700, Varmint Laminate in .308 Winchester.

1-12" Twist

All boolets had 2 layers of liquid Allox applied to the nose section. Most guys wont do this I know. It is not nessessary for sure. But, I HAVE SEEN MY GROUPS SHRINK BY AS MUCH AS 1.5" BY DOING IT.

I have compared the same loads with and without boolet noses lubed. I am thinking it may be hydraulicly centering the forward bore riding section of the boolet. My bore is .3005". My boolets just engrave lightly as they are chambered. The excess lube just flows to fill the void between the nose section and bore. Because fluid is not compressible, I was thinking this would very positively aid in alignment during the boolets acceleration down the bore. Tell me what you guys think of this idea. I am open to ideas.

All boolets were seated to the bottom of the lower lube groove.

Very light crimp was applied to the cases.

Federal 210M Primers

Winchester Neck sized cases (weight segregated and uniformed)

Hornady Gaschecks used

Lyman super Moly lube.

Boolet sized to .310"


I noticed a significant difference with loads that used Dacron and those that did not.
Loads that did not use Dacron filler, grouped close to twice as big.

I tried a few loads with the IMR4350, and filled the space between the top of the powder and the base of the boolet. Even a 1/4" piece of filler really improved the load stats AND the target groups size.

As the charges increased, I noticed a small trend in accuracy. It improved a little each time.

At 41.0 gr. IMR4350 My group was 2.515" (200yds) Ave velocity:2282fps.

At 42.0 gr. IMR4350 My group was 2.400" (4 of 5 rounds in 1.3") 200yards. Ave Velocity 2340fps. [smilie=w:

With IMR 4831, I never used any filler on this trip. So this trial with 4831 was just to evaluate the accuracy of a few loads witout the filler.
Group sizes varied a little differently with this powder.

42.5gr. IMR4831, Group size was 3.234" at 200yds. Ave velocity:2051fps.

44.0gr. IMR4831, Group size was 0.530" at 200yds! YEP thats right! 0.530" (5shots) Ave velocity: 2183 fps. :drinks: [smilie=p::D8-)

45.0gr.IMR4831, Group size was 2.373" at 200yds. Ave velocity:2249fps.

46.0gr. IMR4831, Group size was 2.597" at 200yds. Ave velocity: 2277fps.

I was very pleased with these results! Accuracy for most loads was more than adequate for most shooting needs!
The 44.0gr. IMR4831 load was rediculous! it may have been a fluke, but I will try a few more groups to get a more accurate trending average. I was only 5 rounds.

IMR 4831 seemed to burn surprisingly clean! I think having my boolets lightly engraved into the rifling may have helped the powder to burn more completely.

None of the loads had any pressure issues.
The only thing that I would like to be improved is my Standard deviations. That may take a magnum primer.
I will try that after all my preliminary load tests are done.

Velocity is really good! I am very happy with a 2250-2300fps+ averages!

There is room for maybe 47.5grains of IMR4831 to the base of the boolet. That would be 100% load density.

Hopefully this will get me 2350ish fps without the accuracy falling off, or any pressure signs showing up.

And no filler! Simplifies the loading a little.

Hope you guys enjoyed the update!

Be careful when working up loads with these powders. remember I had my boolets slightly engraved into the rifling to aid these slow powders to burn better.

Take care, straight shooting, and keep it fun!

Fathom that:drinks:

That's the thing with the slower burning powders that ignite easily and efficiently like 4831 in the .308W with the heavier bullet 311299. You get close to loading density and above 80% the filler is not needed:-D

Good shooting, like to see how that 44 gr IMR4831 load does with a 10 shot group.......

Larry Gibson

[Dthunter]

Hi Larry!

I will try at least three more groups with that 44.0 grains of IMR4831.
Just in case it was a fluke. Chances are the average will be close to the same as the others.

I remember reading one of your posts about not needing a filler if a slower powder has a 80%+ load density. So I tried it. My groups with 40-41-42grains of IMR4350(with out Dacron filler added) shot into about 6-8" at 200. Yuck!

So that is why I added the small 1/4" piece of Dacron on the tests of the IMR4350 I shot yesterday/posted today.

That little piece of Dacron made an immediate difference! Wow!

Do you think the Dacron aids in sealing combustion gasses as well as hold the powder charge in a uniform position for better ballistic performance?

[Larry Gibson]

Dthunter

I see it's pretty cold up there and that may have very well influenced the ignition, hard to say though. When at 80 - 85% and you drop the dacron filler the psi and velocity goes down if just the same load is used. It takes a gr or two more powder w/o the dacron to equal those back out. Again, hard to say as each rifle has it's own quirks as to what it likes best, especially with 4831 because it depends on what flavor is used. Loading density with H4831SC occupies a lot less space than the same charge of regular 4831 or IMR4831 so I most ofton do use the dacron filler with that powder.

It's the same with IMR4350 vs AA4350. I mostly use the AA4350 because it ignites easily and uniformly at low psi and meters so well because of the small kernals. It most often requires the dacron filler also, even in the .308W with the heavier 311299.

BTW; Your velocitites with your Rem 700 VL are almost identical to my M70 Targets with 26" barrel. I keep advised if getting a .308W for cast bullets (or a 30-30 or '06 for that matter) to get one with the 12" twist barrel because very good accuracy can be had up into the 2200 - 2300+ fps range. It many times falls on deaf ears because many do not want to believe the twist between a 10" and 12" makes a difference at that velocity level. The use of the dacron filler also falls on many deaf ears because they do not want to believe.

I coat my boolits for my 308,338 and 375H&H, in a light coating of LLA (thinned about 8/1--ms/lla) and I have noticed group sizes shrink quite a bit, using the coated vs uncoated boolits.

[Dthunter]

All I know Larry, and fellow boolet shooters, is that I was a very suprised at this performance!

But now its just pure fun!
Wow, this should really be effective for hunting!
My alloy is 18lbs wheelweight alloy +8 feet of 50/50 lead/tin solder.
Air cooled.

I will try to test boolet expansion at 100 & 200 yards.
Hopefully they mushroom nice.

[Dthunter]

Thanks for your input Larry!

[Larry Gibson]

For hunting you might want to HP them a bit with the Forster 1/8" HP tool.

Shown is my 311299 HP'd (might be the 314299) with the Forster tool:cbpour:

[Dthunter]

Cool! I got mine just two weeks ago!

How deep do you drill your hollow points Larry?

[Larry Gibson]

Cool! I got mine just two weeks ago!

How deep do you drill your hollow points Larry?

If your alloy is soft (I use WWs + 2% tin +50% lead) then about 3/16" is about all you want. The Forster directions say 1/8" But with the long heavy bullets I've found 3/16" works well with that alloy. If you push it to the velocitites you are (that softer alloy requires the barrel be cleaned every 7 - 10 rounds to maintain best accuracy) then you'll have enough retained velocity/energy for expansion to 250+ yards.

Velocity falls off fast because the BC sucks, but that's the price you pay the band to dance:bigsmyl2:

"Velocity falls off fast because the BC sucks, but that's the price you pay the band to dance"


Yes, but I'll bet the BC is pretty good at subsonic velocities...why push those poor boolits so hard? :-) It looks like that boolit with a hp would perform pretty good with no expansion...no?

[excess650]

I just shot some 311299s in my K31 yesterday, and they seemed to group tighter as they went faster. K31 (7.5x55) has case capacity almost identical to 30-06, but body diameter, body length, and shoulder angle are different.

So why push 'em hard? I'm tryin' to hit targets waaaay out there. I've shot my K31 to 900 yards with iron sights and my '06 to 1000 yards with a scope. With the 311299 at higher MV than my current loads I'm expecting to need less sight adjustment and hoping for better accuracy waaaay out there.

[Dthunter]

Excess, what kind of vertical adjustments do you have to make to get to 1000?

I am pushing the Boolets hard for three reasons:

1.) to see what the very top performance I can achieve is.(learning)

2.)to maximize my scopes ability to make long range adjustments.(without having to use more than the 25 MOA rail I already am.

3.) If I decide to hunt with this boolet, 2300-2400 fps will knock down anything I hunt out in my neck of the woods.


I have a load that shoots in the 1850fps range, that I have shot accurately out to 600.
My scope simply cannot give me more adjustment. And I am presently not willing to shim the extra 22-25 MOA (.022-.025").
I just dont want my impact point to be 20+" high at 100, and be unable to adjust my scope to point of aim. I wont be able to use the rifle convieniently that way.

[Dthunter]

Did some more shooting this sat.
I managed to get two loads that shoot at 2417fps, & 2425fps.
One with IMR435 & IMR4831.

Accuracy was 3.5" at 200yds, with the 4350. This powder charge had a Dacron filler.
Accuracy was 5.5" at 200yds with the 4831. No dacron used, because the powder is at 99% load density.

I might drop back 2grains of 4831 and add a filler to see if this will have a positive effect on the load stats.
