Looks like it is coming in.

Gordon, will a little less powder bring the group up to the sights, or a little more? Sometimes rifles react differently to increased or decreased charges. Much depends on stock shape, recoil, and ball speed.

I found in my 14 bore, that 2f and 3F produced the same speeds, but 2F was easier on the patches. In it, more powder increases elevation.

I see you are using FG - what make?
