Alliant Powder

[BarnesX.308]

does any one have, or is it even possible, a load for a 7-08 using rl22

I think RL22 is way too slow for that small case and probably short barrel.

I've had the best luck with that case using IMR4895.

In 7mm-08, it will be worse than 4350 for compression and I love that load. And you will never reach 55K CUP or 60KPSI. You will run out of room with 48gr of RL22 and it will be slow as crap.

I have never tried it. But this is just observations on experience trying slow powder in limited capacity cases like this.

OK
I picked up some H414 today what do you think of this stuff
win 760 is doing pretty good in my 120's varget hasnt been doing good for me in 120's or 140's
Looking to try something new. what you reccomend.

Never shot H414. I have always stuck with IMR4064, Varget and IMR4350. But if didn't like Varget, not sure 4064 will do you any better. I have a bunch of BLC-2 I am thinking about trying.

zrexpilot... I agree with the above posters that RL 22 would probably be too slow for the 7mm08... RL 15 performs the best in my 7mm08 with 120 grain bullets, at least of the powders I have tried.. Haven't tried the H414...

I've had good luck with 4064 with 140 grain bullets...

4895 is a good choice as far as burn rate goes I have never been impressed with it's accuracy in my rifles... With RL15 I get tighter groups and somewhat higher velocity..

I must admit that I've never shot that powder in a 7mm-08. I load for two 308 Wins. But they are the same case so I know the powder is efficient for that size case. Our 308s shoot well with IMR4895 behind 150gr Barnes TSX bullets. I believe the velocity is 2945fps.

WW 760 is a great powder choice in the 7mm-08. I believe Remington used a non-canister grade of that powder in their factory loads at one time.

Thats what I was gonna say Will. Except I thought thats what they still used for their 140 core lokts.


Zrex.. I know all the manuals I looked at here seem to list very good velocity from 760 and 414.
