So had a Deerfield that no matter what would not load the last round (#4) … other than that cycled flawlessly. Well after head scratching and comparing the spring tension in each of my 5 magazines huh? There’s some that are tight and some that are super light. It’s a pain in the butt to do but disassembly , one extra turn on the spring of those mags that did that and boom cycles 4 every time. Just in case anyone else has this issue.

Those Ruger rotating magazines can be sweet if the spring tension is properly set. As you know already, if they are not, they can be a real headache.

I take all mine apart, clean them and adjust the spring tension to be the same. Not bad to do once one practices this task!.......:)
 
lol my first trek into doing it was definitely a pain but going forward I think it’s pretty straightforward albeit a bit finicky. If you have any tricks feel free because there was A LOT of cuss words today 😂
 
Ah, I'm glad someone posted this. I was lucky enough to get 6 of these magazines with my Deerfield, but as mentioned above, two of them would either not strip the last round, or get a partially chambered stoppage. Thought they adjusted like a 10/22 magazine, but surprised to find out they don't. What's the secret?

Basically gotta disassemble… give the mag elevator an extra spin then very begrudgingly reassemble… the first one sucks but works a lot better once it’s done
 
I had to do that with my Ruger 96 to 44 mag. As you said a pita but after doing it the first time it's not that bad imo. None of my Deerfield 99/44 mags do it but they tighten the same as the 96 so no big deal
