Hi, I'm currently using 43.0 gr. of IMR 4064 for my 178 AMAX rounds with winchester brass, cci military 7.62 primers. I get sub moa. What experiences do you have with different powders or whatever you use?
 
Re: Powder for 178 amax in 308.

varget works well,I'm running 44gr with fed brass and they are working pretty good for me at 600 yard on steel.but i haven't tried shooting groups with them yet


loads tested started at 43gr and worked my way up to 45gr

Wow that's a lot of powder. imr 4064 45.7gr... that's a compressed load. What length and twist barrel are you shooting with. I have a 24" 1in10" twist rate and am shooting 43.0gr imr4064 and am getting 2650+/- fps.

I've been shooting varget 44g and 178g Amax win brass and primer at 1K and shoots a little better than 175smk out of 700p

I'm running them at 2681fps with 43.0g Varget in Fed GMM brass, and Fed 210m primers. They work great on deer. they rip a good sized hole. 22" barrel

Im using 46.3gr of RL-15 in Winchester cases with Wolf LRM primers, and 178s seated to 2.940(~0.020" off the lands in my gun). They are chronoing at 2660 but back calculating using my actual dope to 1000 they are more like 2740. Iva got a factory Remington barrel cut to 20" 1-12". I get absolutely no pressure signs even in 100 degree weather.

Varget is all I use with the 178 AMAX. You'll find a good load from 43-45grns.
