I wanted to try and figure out a mathematical formula for converting 3f powder loads to 2f
For example
Goex 3f 90grs= ?? grs Goex 2f
This might be a handy formula for us to work out, so that way people can maximize the powder usage (or minimize it, depending on their viewpoint).
Post away
Industry standard is to reduce 2F load data by 10-15% when using 3F...ie: an 85grn charge of Goex 3F would be 100grns of 2F.
