Serious question: do standard hunting rifles have 20+ round magazines?
Not a hunting rifle, but the Ruger 10/22 is one of the most popular rifles in existence. It's the rifle they teach kids to shoot in Boy Scouts. They make youth versions. You can easily buy 20+ round magazines for it.
Well, in other states you can; not in our state. It's a lot of fun to shoot with the high capacity mags, though.
