What it is good for

  • Elk, mule deer, and pronghorn in open country.
  • Hunters who want flat trajectory and power in a long-action rifle.
  • Long shots where wind and drop matter.

Where it falls short

  • Recoil and muzzle blast are heavy, so flinching is a common problem.
  • It wears barrels faster than milder cartridges.
  • It is more cartridge than most whitetail hunters need.

Field notes

Introduced in 1962, the 7mm Remington Magnum became a favorite for western big game. The belt around the base of the case is a feature of this design family and helps position the cartridge in the chamber.
