Hello, I am new to cap and ball hand guns but am an avid collector of U.S. Army vintage weapons, my latest acquisition is an 1860 Colt Army, 44 caliber, cap and ball pistol. This one was made in 1863, verified by serial number on the Colt website. I want to be able to shoot this weapon but am not sure what size percussion caps to get, I can find nothing online that tells me exactly what I need. Everything I find discusses modern reproductions or later Colt versions of this pistol. Would appreciate the support of an "old hand" to provide some insight on this issue as I would like to be able to shoot this weapon safely. Thanks in advance
