[QUOTE="cb4128, post: 2439183, member: 80069"] In all of my rifles that I handload for - some customs, some factory guns, muzzle velocity and pressure increases when I install a suppressor. In the same range that others have reported - 10-30 fps usually. However, on 2 rifles I have worked up loads with the muzzle brake only and when I switched to shooting suppressed it wasn't shooting as tight - both with thunderbeast ultra 7 cans. On 1 gun, it increased pressure enough that I wasn't comfortable with my load anymore and had to back of a full grain because there were shiny ejector marks and a plunger mark. This was with Retumbo in the same atmospheric conditions as before. I always work up loads with the can on now, and haven't had any trouble with this since. I've never heard or read of anyone losing velocity when installing a can, but I guess it's possible depending on the can design. [/QUOTE]
