I tried that a17. In my 452 was getting 2" groups at 100. Hornady 17gr vmax, federal 17gr tnt and cci 17gr tnt all shoot Moa in my gun
I tried the A17 in my current Cooper. About 1 out of every four cases ruptured where the firing pin struck them. and they shot around 1-1/2" at 100 m. The CCI 17gr v-max loads don't suffer any ruptures, and they average around 3/4" at 100 m for five shots. The Hornady loads were the least accurate in my rifle.
