Well, got the .22 wide magazine Uplula loader yesterday. It works great! No more blisters.
Glad to hear you found something that works for you
But remember:
The 22UpLULA will ONLY load Rimfire Rounds
Unless you cut the Limiting Tab off of the Yoke, it will not open enough to accept anything larger than Rimfire
ALSO, the Beak on the 22UpLULA is shorter
Some Mags out there (and I am NOT talking about the KADET Mags) have shorter Feedlips, and the last Round loaded MAY pivot around the short Beak and pop out of the Magazine
I modded my first Mag Loader for the KADET, not because of Blisters;
But because the front Feedlip on my KADET Magazine(s) were so sharp, they (one of them) literally sliced my Thumb open
At that point .... I'da settled for Blisters !
