Anyone shooting this gun or any Bergara in .300win seen a few post about 6.5 but none on .300…1-10twist doesn’t like 200 or 212, groups got better with 180..it’s and my smith getting bedded before I go any farther. Just seeing if anyone can tell me what works best in there rifle..yes I know each rifle is different like humans. I just don’t want to keep playing with grains…gonna get cheap factory of 150, 160s and 170s I think with 1-10 the lower I go would only get better..then on to hand loads and finding the right dope.
