I load 40 S&W with 180g Hornady XTP using Magnum primers and 4.3g of Titegroup.Griz44, do you load for .40 if so what recipe do you use?
For my Taurus PT, it is accurate and burns pretty clean.
My son also shoots the same reload.
For cast lead of the same weight, (practice and plinking) I use 6.6g of Power Pistol.
Most of what I shoot is 45, so the 40 is not a very regular loading for me.
