I'm almost out of Sport Pistol, and I'm looking for a temporary replacement until I find more.
I've got True Blue, AA#2, HP38, and WST on hand.
I'm loading 130pf 9mm using 124gr coated bullets and Fed SPP, out of a Shadow 2. 3.8gr of Sport Pistol did the trick.
Which powder that I have on hand would be the next best fit?
