Funny you mention them.
I got to try my two out at the range last Saturday for the first time. I have one for my Browning Buckmark, and one for my Ruger MkIII. The cliploader is one slick little unit in terms of using it.
Insert 50 rounds in hopper.
Shake to align cartridges in feed tray.
Insert empty mag, tap once or twice to fill last bit of mag.
Shoot mags.
Repeat.
Voilà! Empty to Full mag in about 5 seconds or less. No sore fingers.
Makes shooting the .22 handguns a lot more fun when reloading times are slashed. I will be using them alot more now for sure, only drawback is you will find yourself eating through bricks of ammo fast.
Picked mine up at brownells. Reasonable warranty, fast shipping, good price.
