I use it in 9x19, 38 Special and 40. All with jacketed (124 JHP, 142 FMJ, 180 JHP) bullets.
9x19 and 38 Special are loaded to low to nice mid range loads. My 40 load is straight out of the book pushing a 180 gn bullet around 950 fps. Nothing crazy.
Good accuracy and somewhat clean burning. Clean when compared to other powders around the same burn rate.
I like it, but I dont push it either.
If you want rip snorting fast velocity, Titegroup is not the powder for you.
If you want to take little micro naps when reloading, Titegroup is not the powder for you.
I did not like it in 45 ACP, Clays or N310 for me there.
