Well I load for a cz so it's going to be a bit shorter then yours. I started with 3.6 grains of SP with an ACME 200 round nose no lube groove, loaded to 1.125. The average velocity was about 835 fps, about 167 PF. (I might bump it up to 3.7 or 3.8) when I ran out of the acme I bought some sns 200 gr, same load data and I actually lost velocity. Averaging like 815, only 2 rounds of the 10 I chronoed actually met PF. When I run out of the sns i might try the blues next, I dont know.
