I'm impressed by how forgiving the load variation is in my GPR. I can go from 30gr 3f to 75gr 3f and get about the same group size.
This is a 3 shot group from a bench at 32yds using 30gr of 3f and this is my squirrel load. I'm not sure what my muzzle velocity is, but even if I don't get a head shot, it just pokes a hole through them without exploding them.
