BPCR and pressures

[Eric F]

I load 50-90 would it be dangerous to load 93gr 3fg in my case to replace my load of ffg? what about 4fg? I know the fouling will increas but I have 5 pounds of 3f and 2 pounds of 4f. I was thinking of a duplex load cutting powders in with my 2fg. Any thoughts.

i wouldn't do that as the finer grained black powders have faster burning rates. maximum working pressures of your gun could be exceeded, leading to a blown up gun or injury to the shooter.

agreed. its not recomended. however there have been people who have done it. just need to be carefull that will surely increase the pressure. I would not try it in 4f though.

I see perhaps I can make a starter charge so to speek say no more than 10% or so. I just got to burn this stuff up and with no pistol or small cal. gun........hey what powder for shot gun loads as in brass shot shell?........Scrat?

you can use either 2f or 3f i have used them both.
