I am working on a build for my wife. I had her look at different rifles, actions, stocks, ect. Let me say she has pretty good taste. So far we are looking at a KMW Sentinel and badger action. What I need help with is caliber. She is use to shooting a 223, but thought about getting her into a 6.5 CM to shoot longer ranges with me. What is everyone's thought about it. She wants a light recoil rifle. Thanks for any advice.
