I don’t own one, but 7MM PRC is very popular right now. A lot of guys are using them. I’m sure some folks on here can give you reviews.
I have been shooting a 7MM Mag since I was 13. I’ve killed elk and mule deer with it, in addition to whitetails and pronghorn. Lately I’ve been hunting with something smaller, mainly to carry a lighter rifle. My last 3 bulls have been killed with a .280 and 30-06.
