    I recently purchased a box of 9mm 124 gr GDHPs. Are all GDHPs +p or are they loaded to standard pressure? There is no indication on the box.

    If it does not say +P on the brass and the box then it is standard pressure.

    look at the case head. if it's +p it will be stamped on the case head, if not it's standard vel..

    For future reference, all the ammunition manufacturers have websites with information on their stuff. Some of the law enforcement versions of their sites will also have gel results.

    Gold Dot makes both a standard pressure 124 grain loading and also a +P 124 grain loading. If it doesn't say "+P" on the box, you got the standard pressure load.
     
  6. As posted earlier, the case head stamp will answer your question. ATK has gel tested that bullet, the standard pressure 124gr GD was deemed a caliber failure by the NYSP after the death of one of their Troopers.

    If the 124 gr +p aren't available at my local cabelas (best selection in this area) what would be a solid alternative? I remember seeing 115 +p core Bon when I was there last week. I will be in Sioux Falls this weekend and hopefully I can pick up better SD ammo.

    If +P is not available, the standard pressure 147 GDHP is also a very good round.

    I believe Cabela's also normally carries the Remington Golden Saber line. They're a bit older technology, but they do pretty well.

    The 115+P Corbons are also effective, but they don't penetrate as deeply as some would prefer.

    After reading a different thread here in caliber corner, I think I answered my own question. Federal HST sounds like a solid choice or Ranger T (if I can find them). Perhaps I will find some 124 +p gdhps from one of the online suppliers. Not really excited about using 147's. No personal experience just gut feeling from what I've read.
    Cheers!

    Not sure what you have read, but the 147s are fine. If you want 124+p, ck "sellforless" on Gunbroker.com Best deal going if looking for bulk.

    He might possibly be thinking of articles that mention the poor performance of 147 grain hollowpoints from back in the day. I think they weren't going fast enough to reliably expand, which was actually a bullet problem, not a speed problem. I thought I'd read that this problem no longer exists today due to improvements in bullet design from all manufacturers.

    Any round can fail and for civilian use I wouldn't personally let one tragic incident (with many contributing variables, I'm sure) cause me to discredit a proven round for my own use.

    ATK's video of the various Gold Dot/Tactical Bonded/HST comparisons shows that under most controlled tests there is very little variation in performance between caliber/weight/pressure configurations.

    I'd be fine carrying standard pressure 124-grain Gold Dot if I had any.
     
  13. Agreed. I spent a lot of time & money reading & shooting before finally coming to the conclusion that most of my caliber & load concerns were simply "picking the fly scat out of the pepper". IM(most humble)O, if you're carrying a rock-solid dependable handgun, 9mm or larger, with conventional defensive ammo, from a well-regarded manufacturer...you should then only concern yourself with situational awareness, sound tactics & effective shooting technique. Because +127 feet-per-second or +.05" of bullet diameter is NOT gonna' save your bacon. At that point - It's not the arrow, it's the Indian.

    I wouldn't feel underpowered in any caliber I was carrying as long as it was GD. They have been proven in every caliber and weight

    Between the Speer 124 gr. & the 124 gr. +p there is not a nickel's worth of difference in the FBI denim/gel tests ironically. Personally, I believe that the NYSP was too quick to change to the .45 GAP because of a few remote instances whereas the perp was a resolute human who didn't want to stop quick enough. That happens with any caliber but the NYSP hit the panic button and changed rounds. Just my 2 cents.

    HST and Ranger-T are great choices, personally I don't care for Cor-Bon, too expensive, I don't care for their style of loads anyway, and the bullets they use are rarely what anyone would consider best in class.

    Today's 147 grain bullets are excellent, some of the best performers out there. And they do better out of short barrels than lighter bullets as well.

    I agree. The NYPD has stuck with 9mm and are quite happy by all accounts I've heard. Their standard issue load is the GD 124+P.

    I recall writing down some stats while I was watching ATK's video a couple of years ago and I discovered them last night.

    Federal 124-grain HST: 13.5" penetration and .66" expansion in denim/gel
    Federal 124-grain HST +P: 14.0" penetration and .60" expansion in denim/gel
    Speer 124-grain Gold Dot: 14.25" penetration and .57" expansion in denim/gel
    (Didn't get the info on the 124-grain +P Gold Dot)


    Federal 124-grain HST: 9.25" penetration and .41" expansion through auto glass
    Speer 124-grain Gold Dot: 9.25" penetration and .58" expansion through auto glass
    Federal 124-grain Tac Bonded: 10.25" penetration and .58" expansion through auto glass
    Federal 135-grain Tac Bonded +P: 10.75" penetration and .51" expansion through auto glass
