Why such a low load? My Sierra book starts at 39gr 4895. I'd say keep working that load up! My 20" loves the 165gr Sierra Gameking with 42gr 4895 (book max is 42.4 or 42.1 for the 167gr Matchking).

I have had good luck using Win748 and IMR 4064 in my AR10 .308.

I have also found that Hornady SST bullets work quite well in this rifle.

Ok, that makes more sense. You might keep working up to the max with the 4895. That is where I found my sweet spot. I also worked a little bit with 4064 but gave up on it when I found the 4895 load that works so well.
