Hey Rokslide, I wanted to post some info that can help to make the right choice when looking for data on 375 Cheytac. I tried searching for load data on multiple powder types before starting this project but could not find anything comprehensive. I'll continue to post results in this thread as the project continues.
A little background, this rifle is a Cadex Defense CDX-40 Shadow 32" 1:10 twist barrel. The customer's goal is to hit 3 miles at some point. We opted to shoot the 350 Grain Lazer from Cutting Edge Bullets. This bullet seems like a great match with the twist rate and has the proven ability to reach out a long ways. We fired 50 rounds to break the barrel in and took this opportunity for a powder shoot out and see where we would go from here. The following are the results:
Peterson Brass, trimmed to 3.016"
350 SMK @ 3.235" BTO
FED215M Primers
Powder and charge rate as shown in the graph:
