That’s my biggest gripe with titegroup and new reloaders. Especially those seeking min PF loads for competition.Titegroup is said to burn at hotter temperatures than other powders, and is therefore not the best choice for non jacketed bullets. I think it is a great powder for just about everything. But, I stay away from it in the 40S&W, only because it is capable of being double, maybe even triple charged in some 40 loads.
When your load calls for 3.5 grains and the case can hold nearly 10... you’re gonna have someone mess up sooner or later.
I ditched it when I started shooting PCC regularly and the powder charges to hit the velocities I was seeking dipped below 3 grains.
