I am new to reenacting and was using a loner enfield armi sport. i had a problem getting the caps on the nipple. the nipple was WAY to big. when i got the cap on it, the tabs were spread apart more than I figure they should be. i could get the caps on, but it took some time. (not a good thing in battle). is this a common thing with armi sport? the overal gun was very clean actuly so it's probably no buit up residue, anyone have ideas on what is causing this, and when i get my own, anyone have a soluiton for the oversized nipple?
