I was shooting the last of the old Varget loads to get them out of the way so as not to have a mix-up while switching to RL15; 44.6 gr Varget under 175 SMK. This is under published upper limit, but in the warning zone according to QuickLoad (which I'm gaining more confidence as a good tool) . I have also had early pressure problems with other Varget loads too, so maybe I have a "hot" lot of powder.
