I just bought a box of CCI Stinger Hyperspeed rated at 1640 fps 40 gr PHP to try in a 22 cal S&W 61-3 Escort that I just installed a new recoil spring on, but was instead thinking about trying them in my CZ 453 American paper/varmint rifle with set trigger adjusted to about 10 oz to see how they would do at 50 & 100 yards.

At the age of 18 when I joined the US Military I swore an oath to support and defend the Constitution of the United States against all enemies foreign and domestic, that oath did not end with my retirement.
