RE: 30-06 or 7mm
I've owned the 30.06, 7mag, and 300 WM. I decided to keep the best 2. The 7mag is gone. The 30.06 does almost everything I could need it for. When more than ALMOST is needed, the 300 WM takes over.
Maybe it was the rifle (Ruger M77) but the 7mag wasn't as accurate and kicked more than the 30.06 (Winchester M70) and the 300 WM (Remington 700 BDL).
