Ok so its Winchester 760 ball powder and i believe it is the same batch, here is what i have done so far.
Re sized the shells oal and full sized them, lube is the issue with sticking in the dye, stroke against 1 shot spray, its shit.
I have loaded 3 at the same weight and 3 with 1 gn less.
Just printing a new target and i will test.
Never had an issue with loading or extracting these shells before apart from shooting in the 30 deg plus range, no chance of that today.
