Thanks Tony,
Wish I had kept the .22 collection I had when younger, it included the .22 long which you refer to, and some .22 tracer, I still had the empty box (Military), untill a couple of marriage's ago! Also some fairground short rounds which as I remember were very fragile and powdered on impact with the falling ducks, seem to remember trying to remove the projectile from one, (picked up from the ground at Billy Mannings Fairground), with a pair of pliers and it just disintegrated. Am I getting too old and imagining these amusement arcade rounds?
Cheers,
navyman.
