Sent off another Email to find out the size in that area. Thanks for the heads up there GM. I didn't think about that. One thing about a Bergara barrel Gm is I would have to use their plug which I heard sucks wind. And why would a get a .45 barrel for a 45/70 from Bergara that I would have to work on when they have 28 inch .45 barrel's for ML's for TC's drop in ready?
The Green Mountain option is certainly a good thought. I have one in my Hawken (lovingly called "the mutt") and it's always been a good shooter with lighter powder loads. But she sure balks hard at higher charges! 90gr's of T7p is about her limit then she starts to pattern like a damn shottie!
