I used the 7x61 S&H cartridge ( belted 7mm Magnum only slightly smaller in capacity than the Rem 7mm Mag) in a 26" barreled Schultz and Larsen rifle for many many years shooting red, fallow, whitetail deer, goats, chamois and tahr from 20yds to 400yds (hundreds of them). I settled on one load and one load only, a 160gr Sierra Gameking Boat-tail in front of 59.0grs IMR4831 for a consistent chronographed 3000fps at the muzzle. This super accurate load never failed on big or small, close or far animals. Never once saw the need for any so called "premium" bullet in this cartridge

Did try lighter bullets of various makes and styles (restricted these to goats) but even the 154gr Hornady did not always fully penetrate goats on shoulder shots. Didn't get the accuracy from Noslers that I wanted.

Wasn't afraid to stoke up the loads as the one listed above was in this strong cartridge and S&L action, here is a pic of what a fired 160 gr factory load looked like, my reloads were not quite there but close in appearance.

It should be easy to repeat this sort of performance in any 7MM Rem Mag with a 26" barrel which all Magnums should have.
