Have read many threads about pinching caps so they will stay on the nipple. While considering buying an 1858 Remington revolver, my brother beat me to it and bought one. Naturally that’s all the persuasion I needed to get mine. Already having #11 cci caps for our smokepoles we put those to use. His first complaint was about his caps flying off unfired cylinders, even though he had pinched the caps with his fingers. So being the tinkerer, I wanted to find a solution, since we can’t seem to get any Remington 10’s. I don’t know how all you guys do the pinch, I got mine to work with some electrical pliers. I put a cap on each end of the jaws and squeeze together. It flattens one side of the cap, which makes it fit tighter. Needle nose pliers also work but the electrical are better. I shot 4 cylinders and had no caps fly off. Was using 30 grains pyrodex P in my .44 caliber pietta with a lubricated wad over powder and .454 balls with nothing on top. Had no misfires or chain fires. Posting this because being a newbie I have not read anywhere HOW you guys were pinching them. Comments and or advice welcome. Wanted to post some pics but don’t see where you ad them to your post.
