RE: 7MM Remington Magnum
The 7mm Rem Mag is probably one of the best magnums ever made. The recoil is very minimal compared to the other mags, it shoots flat, and hits with authority. I have a buddy that shoots elk at some pretty long ranges with his, and he loads 140gr Barnes TSXs up.
So far I've never found a load that my Browning A-Bolt hasn't shot very well. Last year I loaded some very very hot Barnes 120gr TSXs for deer/antelope. The most accurate load I ever made up was a 160gr Nosler Accu-Bond for an elk hunt. That load would shoot 1.25" 3 shot groups at 300 yards off my backpack.
