Over the years, I think I have tried every known type of revolver capper and have been pretty much dissatisfied with all of them. Either the capper doesn't fit well into the nipple recess, making it difficult to get the cap on efficiently, or the caps fall off or get turned sideways in the process. Anyways, most of the time I get frustrated and simply use my fingers.
Finally found a design to my liking. Works on both Colt and Remington models.
