Good post 308Loader.
Name a pistol propellant that I have used, and I can name a characteristic that's unique to it. All propellants are different. I guess that's why they make for such great forum fodder.
The only time TiteGroup running hot is a problem for me (aside from not using lead slugs) is when I am practicing with my Model 67 for competition. I'm shooting six, speedloading; shooting six, speedloading; rinse, lather, repeat. In that situation, after about six or seven speedloaders full, the gun is too hot to handle. I have to put it down and give it a rest. But hey, I'm at the range - how bad can it be? Perspective
All-in-all, I give TiteGroup a big thumbs up.
It meters fantastic. Along with that consistent metering is consistent velocities at the range. TG stands up to the chronograph with low Extreme Spreads and Standard Deviations. And when it comes to the fear of double-charges, etc., 308Loader nailed it: "if this is a concern, I would suggest paying more attention to what you're loading." Perhaps a bit blunt, but the point remains. Don't set a bullet atop a case without checking its charge level - however you need to do that.
Runs super clean. It does get persnickity in 38 Special turned way down. When stepping the charge down, it suddenly gets grainy - but not sooty. I suspect this phenomenon would be much harder to duplicate in semi-auto cases. Furthermore, there isn't hardly any reason to turn them down that far anyway (I'm the exception. I do a lot of odd experimentation with 38 Spl.).
Economical. Not that I choose propellants based on economy (the least expensive of the components). But a little bit really does go a long way.
Stick with plated (or jacketed); load to "range practice" levels; and TiteGroup will serve you every bit as good as any other propellant. And better than most.
