I just changed out the factory Savage 308 barrel for a new McGowen prefit 24" 6.5 CM. Will my zero still be in the ballpark? Or do I need to get up close? My gun had the slick barrel nut and of course i broke the wheeler tool trying to get it off. I heated the nut and action with a torch until it bubbled and the slick wrench bolt finally broke. So i got my pipe wrench and it broke loose immediately. The kick tab did not have a divot to lock into the receiver either, but it did have a slew of Loctite on the barrel.
