I use 32.5gr Accurate 2015, ww brass, wlr primer, remington 125 clsp in my 12" Hunter for 2126 fps, and 1" or less 5 shot groups at 100 yds. For the speer 150 fp, I use Accurate 2520, 33.0gr, ww brass, wlr primer, for 1940 fps and 1" or less 5 shot groups at 100 yds. The same loads in my 16" T/C run about 60-100 fps faster with the same accuracy
