I never see anyone say much about these rifles in any caliber, much less the calibers mentioned above. My 6.5 CM came with a 7 twist BBL and my 300 WIN MAG is coming with an 8 twist. Both are 26" SS straight fluted barrels with muzzle breaks. I shot the 6.5 CM 2 days ago to get it sighted in. Barrel has been broken in. With 143 grain ELD-X bullets it would shoot under 1.25" groups my other 3 6.5 CM shoot thes loads into one hole. I know al rifles (ven of same breed, caliber and barrel don't like the same loads some times) I love the feel of the guns and the triggers are do-able. Have I spent my $1300 wisely?
