Burnt some powder today, testing the above loads.
The grouping was "pretty good" with 13.0 grains of Lil'Gun / 180 gr Cast Performance Bullets / Federal small pistol primers and new Win. cases, firm roll crimp.
It was also "pretty good" with 15.0 grains of Lil'Gun. At 15.2 grains, a primer perforated so I stopped there....... There was also some cratering around the primer hole [ could feel it with my fingernail ] upon firing.
The groups of the loads inbetween these two were poor.
Loaded up some H110 today, with all of the other components being the same as before.
13.0 grains
13.5 grains
14.0 grains
14.2 grains
14.4 grains
14.6 grains
14.8 grains
15.0 grains
15.2 grains
Have a look at Marshal Stanton's [ Beartooth Bullets ] loads on LoadSwap. He's shooting 185 grain .357 mag bullets and a full 16.0 grains of H110. ****! Seems kind hot.
Thoughts??
