    Unless Federal bonded the jacket to the lead core, and then rounded out the nose to make it beefier like they did with their bonded 135gr+P, "tweaking" won't make much difference in its performance against windshields. Their 135gr+P bonded was designed specifically to tackle windhshields. It's harder to make, which is why it is more expensive.

    Winchester's 147gr Ranger Talon does better in the windshield tests than the HST. Probably because the jacket is thick around the nose, and it is wrapped deeply into the nose cavity so that the construction is tougher.

    Tell me, which two bullets pictured below were pulled from P9HST2 and which two bullets were pulled from P9HST4?




    I’ve chronographed multiple lots of both P9HST2 and P9HST4 from a Glock 19 with a 4” barrel. On average, the P9HST4 runs approximately 20 fps faster than the P9HST2 when fired from the Glock 19. BFD.

    We have scheduled P9HST3 and P9HST4 for testing this year.

    Well, I don't know if that's completely fair to say, since the HST and the SXT both do better on glass than some other conventional hollow points. Clearly there have been improvements made in conventional non-bonded ammo.

    Hmmm.... in every shoot I've seen, the 9 147 SXT had complete jacket core separation. When it does penetrate better, it's the core doing so, and the retained weight is substantially reduced.

    Don't know. Which "rep" said that?

    It was Bernie Ness, their federal government rep, that I recall saying the HST had been tweaked since it's introduction. I should have said that before, as I usually ignore claimed statements made by factory "reps" that aren't identified. I'll see him this week at SHOT, so I'll ask and see if my memory is correct. If I'm wrong, I'll amend my post.

    Thank you for sharing those results Mo. Info like that is good to know.

    I'll take a shot and say bullets one and three are from the +P rounds.

    Just found the P9HST1 here in town this weekend for $25 per 50. Not much else on the shelves for carry ammo.

    Im subscribing to this thread as I'm curious. I have been satisfied with the 124+P rounds but I'm open to learning more about the 147.

    Which one would you choose? Why?
    P9HST2... because it is good enough, and who needs the added recoil of the +P...
