My question is for anybody who uses Strelok for 308 FGMM and has good real world results with their cartridge data on the application. Wanted to know what BC you use for 175 FGMM 308? I put in the generic one off of Sierra’s website which was .505 I think, but it seemed a little high. Did a little research and I wasn’t able to see what form factor Sierra uses but no one accused me of being the best at internet searches either.
