John,

The lever throw is only 30 degrees, so a right handed shooter would lower the lever with the right hand, left hand forward under the barrels. Once cases extract, the right hand goes to the stock wrist while left hand loads, and with the short lever throw, the lever in s easily reached with the fingers of the right hand, squeeze the lever up and close the action. I will make a video. It is easier to operate than a typical falling block because of the short lever throw.

Any rimmed cartridge from .22LR (scaled action of course), up to .500 NE
