Nothing wrong with wanting another rifle. I've gotten away from magnums lately but I keep a couple of 7Mags in the safe. I tried a 300 Win Mag but it was more than I wanted. A 7Mag is about the top of my comfort level. It's similar recoil wise to the 30-06 with flatter trajectory. If the chance to hunt something really big ever comes along, I can load it up with a 160 TSX or 175 Partition and not feel a bit under-gunned.
I've never tried a 264 Win Mag, but it does interest me. Maybe some day.
