Finger protection for .223 case preperation

[tooldummy]

This evening I was trimming, chamfering, and cutting the military primer crimp out of some .223 cases on my RCBS case preparation tool. As usual, after about 20 cases the index fingers on both hands were starting to get pretty sore from the sharp necks of the cases. I remembered that .223 cases fit very nicely inside .357 Magnum cases after I had polished some of both cases together in the case cleaner. I stuck the .223 cases inside a .357 and it worked pretty well as a finger protector on the rest of the cases.
