Buck I goofed. I ment 457191, I was thinking of my 45LC mold. I loaded five rounds with the Lyman bullet wiyh 62 grs. of Goex Express ffg. I couldn't hit a 8-1/2"x 11" sheet of paper at 50 yards.
And two out of the five tumbled on me and struck the backstop sideways. My RCBS bullets that are 350 grains work well with the black powder. My Lyman works well with smokeless, five shots less than 1-1/2" at 64 paces.
My mold has a bevel base does yours? Maybe that has something to do with it.
