I have a 444 Marlin TC Encore pistol I use for deer and I am interested in finding out what the program recomends is the best powder to use in it. I recently purchaced some 250gr flat base and 275gr boat tail Cutting Edge bullets to test. I use a 10 inch barrel, but remove the chamber and muzzle brake and it is about 5 1/2 inches of rifling, 1/20 inch twist.
