Where do you get 22 short brass? I can't find it anywhere! I've been playing with the BT Simple set, and made a sweet little lead tip bullet using a short case and a 50.2 gr core with it. Trouble is, I can't find a good way to trim 22lr and can't find 22 short anywhere. I had a box of subsonic 22lr so I got 50 shorts that way for load development. I came up with 24.8 gr. CFE223 with an OAL of 2.135 for a 58 gr or thereabouts, round.
