I've had a couple 7mmMags. I could never warm up to them. Killed a few deer and antelope with them, but more times than not the critter would run for a ways before piling up. Granted if I hit the vertebrae or head it was dead right now, but lung and heart shot deer seemed to always go for a stroll after the shot. I didn't and don't like that. Plus ammo was more expensive, it kicked harder, but didn't seem to hit the animal as hard. Of all the magnums I ever had the only one I actually really liked was the .257 Weatherby and I haven't ruled out buying another one some day.
