Made for Practical range Rifle Twist

Dangerous game basics

Many African countries set a legal minimum of .375 caliber and about 4,000 ft-lbs for buffalo, elephant, hippo and lion. Solids (non-expanding bullets) are used for elephant and often buffalo for deep, straight penetration; soft points are used on lion and plains game.

How MPBR is figured

A 6" vital zone, a scope 1.5" over the bore, sea-level air and a G1 drag model, with sight-in height at 100 yards. Double rifles usually wear open express sights regulated at 50–100 yards, and most dangerous-game shots happen well inside 100 yards, so treat MPBR here as a comparison, not a shooting distance.

Keep in mind

  • Velocities and BCs are typical factory figures from my own knowledge, not looked up.
  • Nitro Express loads are kept at modest pressure for double rifles; never use magnum-pressure handloads in a double.
  • Recoil from the .458s up is severe; practice with the rifle you'll hunt with.
