This cartridge offers a bit of confusion. I’ve found info that says use .323” bullets, in the link provided by Craigster, a gentleman (MECHTECH87) says that the bore is larger, but the original bullets were hollow-base bullets which expanded to fill the bore!

If I pursue this……now, my first step will be to “slug” the bore and determine the actual bore diameter. Then we’ll go from there! However, I’ve never even looked down the bore…..it may not be salvageable!


Thanks to all offering help! memtb
