Get out and shoot it before you do anything to it. They are generally very good-shooting hunting rifles just as they come.

I own 4 of them. 243, 270, 30-06 and 308. All shoot well. The 270 is an especially good one. With 49.0gr of IMR4064 and a 130 Hornady Interlock it goes consistently sub MOA for 3 shots and just a tick over MOA for 5. It's better than minute of deer and frankly that's what I care about most. Great guns. I think you'll be pleased.
