Guys, I am needing a barrel for an A-bolt 7mm Magnum Browning. The barrel on the gun got bent years ago and I want to replace it for my son to use. Where is the best place to get one? Is an aftermarket barrel preferred? Should I change:smt102 the length on it? The one on it now was pretty long and I dont care to shoot over 150 yards or so. I don't want to tie up a fortune in it. I just want the best catch for my money. Any suggestions??
