Bought a cigar box full of odds and ends at the Farmers Market this morning. Some cool old stuff- the coolest being Remington Rockets! These were sold in a "chicklets" pack of 28 .22 shorts. From what I can find they were high velocity, 1600 fps, and had a sintered iron (heck on your barrel) projectile.... no wonder those gallery guns were smoothbores!
The price on the back of the box of slugs looks to be .89. Just sayin'....
