In a N.E.F. handi, I tryed lee 50 cal 360gr improved minie, cast of wheel weights, sized-as cast, lubed with liquid alox. started at 13gr unique but kept blowing the skirt on the minie, worked my way down to 10gr, no leading no more blown skirts, about 3 inch groups off hand at 50 yds, recoil is about like a 2 3/4 20ga dove load. power would have no problem shooting clean through a deer broadside at 50yds and under. keep advized I was seeing some strong pressure sings at 13gr!!!
