Yogi, Long ago I had made some full length shot shells for my .41 magnums using modified .30-30 cases. I found a couple of them while digging through my odds and ends boxes, laid them down next to some standard length brass and noticed the amount of gap between factory brass and the cylinder throats. I'm planning on modifying some more cases that will be cut just behind the throat. These might be able to carry a larger payload of roundballs and/or small wadcutters.
