Yeah, if that's a 1:10 twist, the Berger 185 VLD hunting bullet will get out to 1,000 yds. from a 22" barrel. But I'm betting that the Berger 200.20x bullet will get to 1,000 for sure. Anyway, it's all a wind-judging game beyond 300 yards, and your rifle is plenty accurate. The fun is out to 600 yds. Beyond 750 yds. it's work. 168-175 Federal GMM will get to 600 yds and be plenty competitive.
