This discussion doesn't specify action modifications required to achieve the perfect feeding and function necessary in a rifle used for nasty critters. A military 98 would require significant effort to achieve perfection with 404, rimless 348, head diameter cartridges. A capable factory round that's often overlooked is the 376 Styre. Perfect length for a military 98 and action modifications are quick and easy. Removing the slight internal bosses in the milled magazine box provides the exact width for a perfect stack of 4 cartridges. Open the bolt face from .473" to .500" and you're done. Most extractors and magazine followers work without change. The 3.2+" magazine length allows bullets to be seated out to the base of the neck.

A dandy wildcat is the .416X.376 with no other change than the neck diameter. Velocities with all bullet weights equal 450X400 speeds at easy pressures. What's not to like!
