Backcountry Hunting Podcast

Apr 1, 2022

7mm-caliber cartridges are capable of taking any hooved, non-dangerous game in the world—as long as they're paired with the right bullet. This episode takes a deep dive into the 7mm world, from the historic 7x57 Mauser that started it all up through the cutting-edge modern "sevens."

Focus is on how to get the best-possible performance out of your 7mm cartridge, whatever it might be. We use the following criteria: 

  • Intended use (game type and anticipated shot distance)
    • Big game. Elk up through moose & bison
    • Deer-size game
    • Short shots in timber (tough, deep penetrators)
    • Long shots (accurate, highly aerodynamic projectiles)
  • Cartridge capacity (propellant, which equals velocity)
    • Three categories of cartridge
    • 28 Nosler
    • 7mm Rem Mag
    • .280 Ackley
    • 7mm SAUM
    • 7x57 Mauser
    • 7mm-08 Rem
  • Rifling twist rate
    • 1:9.5, 1:9, and the oh-so-useful 1:8/1:8.5s
  • Barrel length
    • For maximum velocity
    • For use with a suppressor
    • Accuracy in short vs. long barrels
  • Rifle weight
    • Pros & cons of rifle weight
  • Shooter recoil sensitivity
    • Maximizing rifle shootability

Final thought: Hunt the world with a 7mm. Confidently.
