Thread: Hello All

Hi Brycey, subs in the 7mm08 is easy with trailboss, you dont mention your barrel length but start with a case of trailboss up to the shoulder junction (1400fps) and work down in powder weight until you get the speed and accuracy you want, they will go subsonic under 1130fps at sea level @ 20deg celcius or thereabouts.


A lot is going to depend on the accuracy you want.

I had the barrel cut down to est 18.5 inches although I have not measured it since the work was done it will be fairly close. What projectile would you recommend? I cannot find any round nose ones. Running a MAE over barrel.
