A question came up in a discussion with a friend the other day..
In general, what is the preferred powdertype when loading cast boolits for 9mm luger, taken that all other factors are equal?
Sized to fit barrel, boolit weight, alloy hardness, velocity et.c.
A slow burning powder or a fast burning one?
Are any type better suited than the other, in general?
I have never had any luck with lead in 9mm, poor accuracy, leading, unstable boolits and so on, to the point where I have put casting for 9mm aside.
But now, since I have reached such great results in my other handguncalibers, I'll give it a new try..
I use vithavouri powders, and in the manual they lists loads from N320 to 3N38 for the same 124gr boolit..
My goal are top accuracy and velocities around 1000f/sec
