Thanks Hardcase. Well I made my "crimp" tool, works fine. Caps come out round instead of oval and fit the nipples not too loosely but still can be removed with my fingernail. This is UNFIRED. I've not shot any yet. We'll see. At least I've moderated, if not removed, a potential chain-fire factor. I'm retired, so have (maybe) too much time on my hands. Anyway, crimping is easy and fairly fast. I lay the cap on a flat surface, place the "crimper" around the skirt, a little squeeze and voila! they fit. I'll just do as many as I think I need the night before I want to shoot.
Not much c&b revolver going on in my locale. Hoping someone here'll start stocking Rem #10's in the mean-time.
