I load for my G17, XDM, several variations of Taurus including PT111, 24/7 and a Millenium Pro. All of them get the same diet of everything from a 90 gr. XTP up to the 147 gr. XTP and Gold Dots using Longshot and HS6. Velocities and accuracy are excellent with both of those powders. Pressures appear to be very stable even though they are in the higher working range. I like those powders because they are not temparmental even when I'm loading above the listed maximum's for those bullet weights.
These powders are not going to give you a low end option though, and are only intended for a high performance load. They are fairly slow burning powders for this cartridge so powder charges are dense and make it easy to notice an accidental double charge because it won't fit in the case..
