Due to the fact your 22 short magazine has no markings It's not necessarily from Winchester. I haven't noticed a 22 limited journal which was not the same outdoors dimension as 22lr mag. I'm able to’t consider how a mag, such as you explained, could possibility be secure when inserted. https://highimpactrounds.com/product/winchester-xpert-20-ga-2-75in-6-3-4-oz-1325-fps-game-load-25-rd-box/
