I was asked to find out if it is safe to shoot 7.0 gr. of Red Dot behind a 200 grain bullet in a .308? I ran it on QL and it says it would be around 1150 fps, 20,000 PSI, and 35% case fill. The gentleman wants a subsonic .308 load to shoot with a can on the end. From what I researched, most guys use Trail Boss. He has a bunch of Red Dot and wants to use that, if he can.
