30-06 - h4895 - 157gr gc boolit - 26-2700?

[number7tn]

anyone have a load for a 30-06 using h4895 powder with a .309 gas check 157gr boolit. would like around 2600 to 2700fps ,,,, i have used unique but just wanted to try a few a that is a little harder hitting.

if it leads my barrell ill cut back a lil or go back to unique or something else , this is what i have right now , the h4895 , also have some h1000 i can use if it would be better at about the same 26-2700 fps

im thinking around 43.5 to 44gr h4895 should be close.
oh im using standard fed lr primers if it makes much diffrence.
any help is truley appriciated.
thanks,
GOD BLESS

Darrell,

Getting cast .30 cal. bullets to shoot accurately at 2,700 fps has been a goal for over 100 years for bullet casters and reloaders.

VERY FEW have succeeded .

If I could suggest, starting at 1650 fps and moving up the ladder in velocity until your accuracy " goes south ", that would be my approach to a max. speed load with IMR 4895 or H-4895.

I have great results with IMR - 4895, but not at 2,700 fps.

Here is a target I fired ( 5 shots @ 50 yards ) with the 311413 sized .310, 24.5 grs. Surplus IMR 4895, Fed 210 in My Ruger # 1 , Stainless , .308 Win. :

+ 1 23.5 Works good for me

It's easy if you paper patch your boolits, but not going to happen if you don't. In 1:10 twist barrels I have never had much luck past 2100 fps. In a 1:14 twist you can go on up past 2600 if the throat and boolit match each other perfectly.

+1 on Nobade's comments. I load/shoot cast in a half-dozen .30-.31 calibers and, without paper patching, I have never been able to get accuracy to hold up much past 2050 fps...regardless of boolit design/weight. On the other hand, the RCBS 165 SIL, launched from my 'as issued' Garand at just over 2000 fps, will easily outshoot all but factory match ammo fired from the same gun. Likewise, my favorite practice load for my McGowan-barreled .308 (1-10 twist) uses the Lee 309-200-1R at 1980 fps and will easily print 1"-1 1/4" groups at 100 yds; less than a half m.o.a. greater than my average group size with 168 gr. SMKs @ 2650 fps.

+2 on Nobade's comments. Getting 2700 FPS is a snap. Getting it to hit the berm, not so much. BTW, you'll need something like 4831 or RX 19 or 22 to get you there.

A ten-twist can be made to shoot at very high velocities, but it takes a LOT of work. Paper-patch is by far the easiest route.

ok thanks for the info. i used the data from the reloader refrence with unique , in 3 diffrent guns/calibers , i think 11gr in 30-30, 14 or 15 in 06' and 22 in 300wm. all was very accurate , well as good as i can hit them default paper targets lol.

i was kinda afraid that was what i was gonna hear , i was just thinking of messing around with about 5 06' cases i had and was hoping for a little harder hitting and less drop at 100yd.

i have been doing a little reading on paper patching and just kind of learning all i can.
anyway thanks for all the helpfull info. its really appriciated.
GOD BLESS

Load some over 18.0 grains of Unique for a Lyman book velocity of 1852 fps and pressure of 34,300 psi. (From 160 grain #311672 data) That will give you a load that almost certainly will shoot good and be a bunch of fun at 200 yards and under. Then try to out do that with the 4895 loads. 32.0 grains of 4895 will start you out around 1,860 fps. At 44 grains you should be up around 2,600 fps.

A fellow with a good 30-06 barrel got my Lyman #311672's going around 2,400 fps with a little over 1 MOA accuracy. That's a 160 grain SP. They were cast from 2:6 alloy air cooled. Lubed with home made Felix lube. So they gave a 5/8 to ¾” group at fifty yards. Slowed down and he may of been shooting one hole groups at that short range. Usually with a 10 twist 30-06 1,950 is about as fast as they like to go with accuracy.

If all you are looking for is groups under three inches @ 100 you can go pretty fast most cases. However accuracy trumps velocity every time. With a 100 yard sight zero those 1,850 fps loads only drop about five inches at 200 yards. If you are shooting fast loads with a three to four MOA group instead of a slower load with a 1 ½ MOA group it’s not even a contest.

I'd not be to shocked if you could get 2,300 fps from your 30-06 with under 2 moa accuracy.

thanks GabbyM, that is what i was looking for , kinda where to start at , just playin around with em , in this gun. yea it is a 1:10 twist 24'' factory barrell. hadnt shot much lead in it except for the unique loads i minchened earlier , i will go up grain at a time from the 14 to 18 with unique and might play with h4895 at the lower end and work up. i am gonna have to get more unique , im almost out , i like it a lot on my 45 acp , does lot better (for me anyway) than red dot, lil dirtier and i like red dot also , and latley have been using 7.4gr of power pistol and a 200swc and that does good in it. only other powder i used in it is tight group and while it shot ok , they was just not enuff fluffeyness to it and i got tired of usin filler.
sorry to have got off the subject . what load would youall start with and how far would you go with the same 157gr boolit and unique in a 30/30?

thanks for all the good info. i really appriciate it.
GOD BLESS

In the 150 - 160 gr weight range the Lyman 311466 or the LBT 150 SP are the best bet to get any decent and consistent accuracy above 1950 fps (top end of the RPM threshold for a 10" twist). With those, if you do everything right in casting and loading you can push the velocity to 220 - 2300 fps with either of those bullets in the '06....if the rifle and you are capable.

For better accuracy under the RPM threshold (1950 fps) with that weight bullet I would shift to a slightly slower powder than Unique such as 2400, 4227 or 4759 and I would use a dacron filler. That is exactly what I do with my own 160 gr WFN bullets pushed to 1900 fps for small/medium game out of my '06s.

thanks for that info Larry. ill try some of the powders you mentioned soon as funds let me. i have used filler on straight wall cases but never on bottleneck. but ill try it, cause i dont really like to ave loose fitting powder in a case, i guess thats how to explain it. i like fluffy powder when they will do the job, not really compressed but at least 90 percent to the seat depth if possable. . the h4895 is just what i had to load em with when i posted this and was just kinda wondering. i have a 200gr lee mold on the way now to try out so i might be back with a few more ??'s.

thanks everyone for the replys and info i appriciate it.
GOD BLESS

I have no choice but to run my '06 rounds fast= Rem 7400! To get the rifle to function I have to run my 150-170 gr cast at or around 2200 fps with 40 -43gr IMR 4895. I had pushed them to 2400 fps but accuracy went south.

[Moonie]

35gr of H4895 and 170gr Lee boolits function perfectly in my sons 742, should work fine in your 7400.

We have not crono'd these loads yet.
