Hello gents,
I'm working up some subs for my newly built R700 308 ACC-SD. Thus far I tried 9, 9.5, and 10 gr of TB and Laser Cast 170 gr RNFP's and I'm still above the supersonic threshold at about 1210 FPS. Going to load up 8 and 8.5 gr and see where I'm at. My primary question is it ok to shoot cast subs through a muzzle brake ? Right now I just have a thread protector on my barrel but I did purchase a brake to shoot standard rounds at my 600 yd range. Thanks in advance !
