[QUOTE="MarkTheFark, post: 2017496, member: 114031"] [U][B]UPDATE 01[/B][/U] I have received some questions about load development with the Hammers, as well as questions about factory ammunition I have tried and what types of speeds I was getting at 20". During the first 50 rounds of the new barrel I tried a few different factory offerings, especially from Berger. The price for the quality on their ammunition is good — especially since I was trying to stock up on Laupa brass anyway. I shot some groups with 3 different Berger offerings, and also rung some steel with cheap S&B ammunition.
