I am a proponent of the in-lines. I had a snail capper. Did not work on the Remington, eventually suffered a catastrophic failure during a shoot, not sure what happened, but spring caught on something and all caps went to the ground. Moved to in-lines, but converted the Remington to some of these, not sure they will catch on, self contained cartridges. I now have about 11 in-line cappers. Loading is the tricky part and have been known to beg with my wife, she of the delicately long fingers, to help. Once loaded, I have not had an issue. And with 11, I can pretty much shoot an entire match and not have to reload one on the fly. I get cabelas/bass pro gift cards for holiday/birthday. Pretty much every time I go, I bring home a capper. I did buy one of Ted Cash's shorter ones. It is good to load a revolver once. I like the concept, but have moved it to the single shot box, as I like having the option for more, in case I drop them.
