I wanted to get away from the 32-20 lube/clean cases to resize and have that easily acquired 30cal. barrel for stub, and the rimmed base. Also, I should have mentioned, that my intention is to use cast bullet loads, not 30C class loads, though with a well done chamber and the almost straight case the should be no pressure issues. As I said, with this idea, if you have and want to load and shoot 30C, it should work fine too. If H&R were making 30C chambered Handies I have no doubt someone would have already done a rim cut and be doing this.
