I went to the range yesterday and tried a couple types of .22 ammo in my CZ 452. The first box was Remington Subsonic Hollow Points (nearest I could tell, pretty much the same as the Thunderbolt). It is the only ammo to this day which has jammed in this gun. 6 out of 50 rounds refused to go in the chamber and had to be ejected. However, when looking at my shooting, it was the tightest group all day - about 40 rounds in a 4" circle at 100 yards and all in the black. The CCI Mini mags, which my gun loves to feed, had the worst group. Then was the American Eagle which also feed beautiful and were almost as tight as the Remington.
Due to several factors (barrel heating, fouling, etc.) I plan to test this a couple of times in different orders to see if I can repeat the results of the test, but I was surprised to see that the ammo that barely fed in the gun actually shot surprisingly well when I could get it in to the chamber.
