sold22 Magnum Ammo

I have eight full boxes of 22 Mag that I can’t use. I bought these locally within the last few months. They don’t work in my Keltec, but they’d be great in a rifle or revolver.
$80 for all 8, plus the partial box of 20 rounds.

Are they 50 round boxes?

Correct, standard 50 round boxes plus a partial box with 20 rounds left after I shot one magazine in my PMR30. The PMR30 is very finicky with ammo types.

I am very interested in these if you still have them .

Ammo sold already. Thanks
