A cartridge diameter difference of 1/8th inch?!?! That’s a BIG difference for a cartridge let alone the actual bullet. You sure you don’t mean 1/32nd or 1/16th inch?
Cartridge length, not diameter.
1 1/16” diameter round? And we thought the 50cal was a Hoss.

Not diameter, height. Different manufacturers have different lengths of bullet. My Rugers fire them all. But the Kahrr only fires the shorter ones.
