Great choice and good for everything in NA! IMO, the 7 and 30 cal magnums are some of the most versatile cartridges around. My rifle really likes Barnes 160 gr TSX and it's killed everything from whitetail to moose cleanly for me. The 139 gr LRX has a higher muzzle velocity and the 150 TTSX has a higher muzzle velocity and BC, but my rifle likes the 160's best <shrug>.
I've had a 7 rem mag for 10 years and love it. I've replaced it with a switch barrel Nexus 6.5 PRC and 300 PRC, but if I'm honest with myself that was mostly new rifle-itis, not because my 7 RM wasn't great. In fact, if the 7 PRC had been out when I ordered my Nexus, I'd probably have one of those instead of two barrels that I switch back and forth.
The 7 mag's are just such a great combination of terminal performance, reasonable recoil, good ballistics, and availability.
