Thanks. In over ten years of shooting my Wolverine with number 11 caps I've only had a misfire once. That was last weekend. It was my own fault. I got sloppy. I had cleaned, lubed and stored the gun after killing a first day deer. When I got the gun out of my safe, I forgot to fire caps to clear the nipple before loading. Took multiple caps and probing nipple with a needle to get the gun to fire. That's why I was considering shotgun primers. But, I think I'll just be more careful and stick to number 11's.
