Optimizing 7mm Performance for Hunting

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.
