Has anyone ever used the .22 auto Ultimate Clip Loader by Arms and Ordnance Research. It' s the one where you dump in a box of 50 rounds of Long Rifle .22 and push a clip from a Ruger Mark II, 22/45 or Browning Buckmark into the bottom of it and it' s supposed to load 10 rounds into the clip in a matter of seconds with no sore fingers afterwards. The going price seems to be $30 everywhere I see one, so I would like to know how well they work before I plunk down that much cash for one. Anybody have one or know someone who does?
