[QUOTE="Montana'eer, post: 2140259, member: 113417"] That web article I linked to in post 2 has a table of powder and charge weights (pet loads), many from competition shooters. Years ago guys dug into Federal GMM 168 factory loads and figured out their secret sauce- so I used that as a baseline. Started at 43gr IMR 4064 (which is slightly above baseline) and 43.3 was the sweet spot. That was with virgin Peterson brass. [URL unfurl="true"]https://forum.accurateshooter.com/threads/what-load-duplicates-federal-gold-match-w-sierra-168gr-bthp-in-308.3866882/[/URL] On the above site on pg.1 there is a military spec sheet from 2009 that shows IMR 4064, 41.745gr under a 175SMK bullet. Case capacity will vary by manufacturer and can also vary in the lot, and from lot to lot. Pick a good quality brass, get a Sierra load book or do some research- start low and work up. The .308 is fairly forgiving. [/QUOTE]
