Got this reply from Big Horn Armory.


Robert:

Lever guns are always finicky about OAL and bullet shapes. We have adjusted the ramps and cartridge guides to make more of them feed well, both fast and slow speed. In general, most cartridges will feed well when cycling the action slowly.

Bullet shapes that work best are the large meplat types.
