I have just started to use it and have run into a snag (I think).
With Goex I use 70 grains of powder and it is perfect to seating the boolit out where I want it.
With Diamond Back (same granulation FFG) I need to add a cotton wad to get the same seating.
If I increase to 75 grains I do not need the wad.
How much pressure increase will I get if I increase to 75 grains.
May not be a problem in some of the newer guns but in the old antiques I shoot it has to be considered.
