About 55 or 60 years ago I used to have a Remington rolling block .22 that shot shorts. Most fun shooting, cheap and it taught me to shoot only once.
I’ve got one of those tiny #4 Rolling Blocks in .22 short. Actually shot it at a long range Cowboy match. Longest target was a small steel buffalo at 250 yards. We had to take out our ear plugs to hear the bullet hit.
