The 2nd picture is a small Altoids tin, not the normal size so that might give a clue as to the size of the cartridges. Also note the size of the bullet holes compared to the dime in the target pictures.
OK I'll bite, .17 Hornady Mach 2. they appear to be .22 LR cases by the size of the tin, and .17 size bullet. They look too small to be the Winchester Magnum Rimfires, and the bullet looks very much like the .17 Remington Fireball, which shares the same cartridge as the .222 Remington Fireball. The Farm & Fleet in Wisconsin has the .17 Fireballs in stock, and they look to be much longer than what you picture, so thats my guess.
Am I close?
