I was looking at adding a second rifle or replacing my current 308.
If your rifle is "brilliant" take it from me and don't replace it. I once had a 30/06 that would consistently shoot sub MOA and I sold it to get a 300 Winchester Mag. Twenty some odd years later I'm still kicking myself
If you want a second rifle I'd look no further than the 7mm Remington Mag. Accurate, powerful, and low recoil are just some of its good points.
