to Armed In Utah ....its a .308 Winchester .....mostly mild to medium handloads. I put about 150 rounds or more thru it every month. Love this rifle!!! I am so used to it now that it feels like a part of me when I am shooting. I have shot as well or better than a lot of other guys who have more money invested. I do shoot a lot more than they do I am sure..... Thanks everyone for your input.. I feel better with that info since I know I am going to wear out the barrel eventually at this rate.
