I had test loading subsonic round as publish on reloading manual.
8.0 gr of Titegroup with 168 SMK , COAL 2.800" chrono around 1,080 fps
But just wonder my new rifle with tight bore barrel (.299/.308) has a short chamber which measure 168 SMK to touch land with COAL @ 2.760"
So, if I seat my load at 2.750" , thus will increase mv of them?
Is it safe to reduce powder charger lower than 8.0 gr?
