I noticed that aquarium hose fits snugly over percussion nipples (use to use it for cleaning a rifle) and I got to thinking maybe they would fit over caps and hold them. What I was trying to do was to make a cheep capper which didn't work so well ( the caps wouldn't come loose from the tubing) - But I had another bright idea maybe if I cut a bunch of small pieces it would help me handle them when capping. So I cut a bunch of small pieces and placed them over the caps. I then ran them through a cap sucking 1860 of mine. Lo and behold all the caps were easy to put on and held the caps onto the nipples intact after firing eliminating any cap jams. The tubing is just barely smaller than the cylinder nipple area and held the caps in place. I ran through 6 cylinders and not a cap came off and stuck in the action. This was surprising because the caps were #11 instead of #10 that fit a little tighter, with the 11 notorious in my gun for falling off and jamming the action. Any one try this and if so how did it work for you?
