Tim Sundles dives into one of his all-time favorite classic cartridges: the 7x57 Mauser (also known as the .275 Rigby). In this episode, Tim explains how Buffalo Bore’s brand-new 7x57 loads perform in real vintage Mauser rifles. Tim breaks down bullet choices, real-world velocities, pressure considerations, and why solid old Mauser actions can safely run modern performance levels when they’re in proper shooting condition. He also showcases three beautiful, century-old rifles used in testing. The episode also explores barrel length differences, game applications from deer to Alaskan-Yukon moose, European and African history with the cartridge, and why Tim plans to take his 7x57 back to Africa for large-scale terminal testing on plains game.
