RCBS X-Sizer Die
Anybody used one of these? They sound too good to be true. Primarily interested in them for 220 Swift, 22-250, and 223. Do they size enough to feed through a fairly tight chambered AR15 ( only 223 applies here)? Do they really limit case growth, or just fool you into thinking this by having you trim .020 off case length at the start? Any feedback at all would be appreciated. Thanks, Andy
