I guess that's how many fairies could dance on the head of a pin ?? LOL Good one Gary !! BTW belated Happy Birthday.
So, probably won't get a lot of multiple loadings out of the .32 spl. brass. If the barrel were rebored and set back, the chamber dimension problem could be overcome.
I realize it's not possible but I would be very interested to know what year the rifle was reworked.
