I guess I got lucky....I tried a new powder and these bullets for the first time, and they shot great out of my CZ 527 American. I used 26.4 gr of Ramshot X-terminator, LC brass and a CCI SR mag primer. I think I read about that load from somewhere. The max shows as a couple grains higher, but this load shot so well that I am just going to leave well enough alone. The first group was about 1/2-inch, and as I adjusted the point of impact with the scope, the groups got smaller. The last 3-shot group, 1 inch high at 100, looked like two bullet holes touching. I did start with a barrel as copper-free as I could get it.

1:12 barrel??
