As I told Tim earlier, I believe the chambers have a step down to prevent loading .44 mag ammo in this gun, generally only a thousandth or so. The ring imprinted on the jacket sort of confirms this to me. And Hawg is correct...you can't just seat them .050 or more deeper without knowing if there is space between powder and base of bullet...compressed smokeless charges are a no-no in most cases. And if there's any sort of crimp, you may bulge the case mouth. Only practical way to go is pull the bullets, resize the cases and reseat bullets to the top of the cannelure. That's IF there is adequate clearance for the powder.
