Snakeman - I use Universal Clays. Meters great through a Dillon 550B, and burns clean like all the Clays powders. My current load is 6.6 grains under a Rainier 155FP. I`m using RP x1 Brass with WSP`s, OAL of 1.126, with a .421 crimp. The load averages 1175 fps with no pressure signs from an HK USP. Work .40 loads up carefully. Tree Rat.
