When I was a kid, for many years I shot nothing but .22 Shorts. At that time they were a quarter a box at the local mom&pop grocery store. LRs were 40 cents a box, way too expensive for me. I still have a sizeable inventory of .22 Short SV ammo (I have one of those Hi-Standard Olympic Rapid Fire pistols also). I happen to own a Remington 550-1 .22 rifle, and one of its many benefits is that it will function reliably in semiauto mode using .22 Short SVs. Makes about as much noise with those as a pellet or BB gun. In my opinion, there was never a better .22 semiauto rifle made than the Remington 550.
