At the risk of coming across as a "smart ass," I'm going to suggest stronger thumbs are needed to load the magazines in question.




Just kidding, Red.....no offense intended. You know I have great respect for naval aviators and NFOs.

I know it's not any help but, the Ruger BX-25 magazines made for it's 10/22 are the only experience I have with 25 round .22LR magazines and they easily load and function without issue.
