I've loaded TiteGroup a lot. Like A LOT. We used to use it in manufacturing due to it's low (and consistent) charge weights, and Dillon powder measures loved the stuff.What was the reason you choose TiteGroup?
9mm 115gn - 4.8gns
38 Special +P 125gn JHP - 4.8gns
40 180gn FP - 4.8gns
45ACP 230gn Ball - 4.8gns
A lot of other powders were using 5.5-6.0gns which doesn't seem like a lot until you're loading 50k rounds of something. It also didn't have a sharp muzzle pop like some powders (HS-6, Lil Gun, Longshot), and most importantly, it didn't need to fill the case. 357 target loads, 45 Colt target loads didn't matter with low charges, they all shot consistently.
It was also very available in the mid 2010's which was attractive, and it was temperature stable. We didn't have to re-key machines much.
There are certainly more beloved powders out there - Bullseye, Unique, 231, etc, but we used it for the reasons above. Just my two cents.
