I believe the bullet you asked about is this one, beside a Barnes 125TAC-XP. I use them very happily in my 357SIG-calibered pistols. They're lightly jacketed, as are all the inexpensive HPs I'm aware of, and hence aren't suited to Personal Defense, but they hold together at high velocities so are well suited for full-power practice loads.
The 357SIG will propel 147g. bullets lots faster than the 9X19 will, but I prefer lighter bullets for no rational reason.
What's your purpose with these loads? Practice? Competition? Personal Defense? If the latter, I use the overall-best (IMO, of course) bullet my money can buy, the Barnes TAC-XP solid-copper bullets.
I found the 'magic' powder for the 357SIG and this 125g. bullet (HS-6), producing high velocities (c. 1360FPS @ 10'), safe pressures, and very low muzzleflash...AND...it fits in the case under that loooooong bullet.
Less-expensive bullets well suited to PD are the Speer Gold Dot and the Hornady XTP. The latter is my favorite 'affordable' 124/125g. PD bullet. Gold Dot on the left, XTPs center and right.
