Re: 308 ammo help
When you say federal comp. style ammo, are refering to Federal gold medal match.
If so, you are already shooting the best.
For what its worth. At one time the Marine Corps was very fond of Federal 210 match primers, 42.5 grains of IMR 4064 and 168 Grain Sierra Match kings. I think now we have moved to 175 grain SMK and am not sure on the powder charge.
