When I started shooting Colt black powder revolvers back in High Scool (1970) it seems I remember the caps were thicker. Never having a cap jam,ever. The fact is,you had to take your finger nail to remove the spent cap off the nipple. The caps came in a blue plastic container like the steel Remington caps do now. I think they were made in Italy. They were the only caps that I could find at the local Gun Shows at the time. Anybody else remember these? The gun was an 1851 Navy steel frame,.36 cal. I remember it was accurate as hell. The older you get,the better you were. Anyway,just asking.
