Mine is the one JC made on the CZ. I must admit, I haven't shot it much, maybe 50 rounds, but it is very accurate and it's easy to get to that accuracy because most of the load work is already done. The .19 really is a nice blend of the velocity of the .17's and the wind resistance of the .22's. If I wanted a gun for varmint colony shooting, I would definitely buy it again. The cases are really tough little guys, kind of like a mini .221 Fireball. The .19's are a lot easier to get powder in and the bullets are easier to handle. Obviously, you need to be a reloader. I bought it to go PD hunting, but never have. It would shine for that or ground squirrels. It won't foul as much as a .17, and should not heat up as much if fired at the same rate as some other rounds.
