I used to shoot them all the time when I was a kid because they were cheeper.I guess this lets the cat out of the bag on how I am an old fart.Would have been 1966 or so when I was turned loose with granddads gun in the small gravel pit that was out in the woods behind our house. Shorts,longs,long rifle were priced 35 ,50,75 cents or thereabouts. Granddads gun was a J.C.Higgins (Sears brand) that was a tube fed semi auto that had a cross bolt.If you pulled out the cross bolt it would fire semi auto with Long Rifle ammo.If you pushed the bolt home it would feed and fire shorts or longs single fire and became a straight pull action.It had a god awfull long barrel and tube,I remember it holding at least 14 long rifles and like 20+ shorts.Surper ulgy brown wood grain plastic stock but I loved that gun even with the crappy buckhorn sights.I still have this gun and need to get some springs and get it up and running just for the heck of it as I haven't shot it for 35 years.This gun was built by savage for sears I think.
I still will shoot the odd box of shorts in my henry golden boy or one of my revolvers,sometimes for the fun of it ,sometimes when going after pests in the backyard.I have an old clip fed rem bolt (511?) but the shorts don't feed real great so it usually ges shot with cb longs. (power of a cb cap with a longer case)
Clark makes a short conversion for the 10/22 which is a bolt and some springs,I have seen it in the midway or brownells catalog but not handeled one in real life.It looks like it could be a hoot but I believe it is like $290 (yow!)
Some of the hot shot rimfire pistol competitions are shot with shorts (rapid fire?)but we are talking about crazy $2000+ European guns
At one time the rumor was that out of a short barrel revolver (4" or less) a high speed short actually has more energy as the light short bullet (29gr vs 40 for the lr) gets up to speed faster and the long rifle never burns all its powder in a short barrel.Some day I need to get to the range with the chrony and test this out
