Took a mini tubing cutter and modified it to allow 22 cases to be made into caps. Head off powder out.... the rim in the groove and tighten the wheel gently to make the initial score on the case . Again tighten gently and rotate back and forth with needle nose pliers. And you will wind up with a cap that works on the first strike. Wanted to come up with a way that was faster and safer and this is what I came up with. 10 bucks for a couple of boxes of22,s so if you make all 100 it will be 10 bucks. An alternative for when regular caps are scarce or to lessen the current demand on your own stock of caps. Best SM
