It also depends on if you want to pleasure shoot very often. I have a braked 300 norma. It is not my pleasure shooting rifle. Ive owned, loaded & shot the 300 win mag also. For balance of power & some pleasure shooting a 7mm is about just right for me. I do own some 6.5s. They are perfect for abusive back to back pleasure shooting cause im not so concerned about shooting the barrel out of them. The big 30 Cal's I've owned: I get them dialed in, occasionally shoot for verification and hunt with them when needed. Not a whole lot of ringing steel constantly with them for me.
