Have some .44mag ammo, I call it snakeloads...
I forget how much the .22lr holds, but I was surprised how much, I think it's #11 or #9 shot??
for snakes it would probably work, what's the use? I don't think for birds... maybe a squirrel in a treestand... or snakes... that's about it...
Probably won't cycle a semi-auto...
