    The Double Tap Ammo company's 115 gr. .357 SIG Gold Dot was last offered in 2009.

    It's now available as the identical Bonded Defense JHP
    that uses the Gold Dot bullet.

    [​IMG]

    A bit lighter than the firm's 125 gr. Bonded Defense
    load.
    http://i204.photobucket.com/albums/bb26/czrami/DOUBLE TAP 357 SIG/dt125-1.jpg



    This load has an advertised velocity of:

    1550fps / 614 ft. lbs. 4"bbl

    With these numbers for other barrel lengths:

    3.5" barrel - 1494fps
    4.5" barrel - 1612fps

    [​IMG]

    It should be a real screamer if it is as hot as the
    NOSLER 115 grain load at:
    1550fps / 614 ft. lbs. 4"bbl
    [​IMG]
    3.5" barrel - 1494fps
    4.5" barrel - 1612fps

    That load exhibits some muzzle flash, but a lot of bang.
    Noticeably- faster than the 125s and 147s/

    Note, that like Nosler load, the once again available DT 115 gr.
    uses a flash supressed powder for virtually no muzzle flash
    as well.
    [​IMG]
    Both should remain the fastest in the DT .357 SIG line,
    except for the DT 80 gr. Barnes TAC-XP:


    1725fps / 529 ft. lbs. 4.25"

    3.5" barrel - 1600fps
    4.5" barrel - 1755fps

    ( the load I carry in my RAMI P)

    And have some appeal to those looking for truly smoking hot
    .357 SIG ammo.

    (All of these numbers are advertised, and your actual chrono results
    will probably vary).


    Thanks for looking, I hope to get out and shot some of this 115 grain fodder.

    The 115gr GD +P+ 9mm load @ 1400 fps barely gets 9" of penetration. Pushing the same bullet even faster will most likely yield even less. All three of those light loads have zero appeal to me for self defense and are entirely too expensive for target practice. I do not know why anyone would waste money on either unless all they want to do is brag about energy numbers on paper.:dunno:

    I loaded & played with some 90gr XTP-HP @ 1700fps in my G31! In my wet media at 10yds it only got a little over 4''! But my friend was amazed at the BOOOM that load made side by side with his 10mm.

    I keep 90gr XTPs around for my .380 and loaded a bunch up in .357sig. They are fun on steel for sure and if you want to make small animals explode. That is about it.

    Since my only reason for owning handguns is self-defense I see no advantage in pushing what is essentially a 9mm round to hyper velocity. I like the light weight 115-grain in 9mm; not in the more powerful .357sig.

    Besides the excellent 125-grain JHP bonded and non-bonded .357sig rounds already available I'd like to see a Speer Gold Dot 147-grain and/or Remington 147-grain Golden Saber along with a Federal 147-grain HST in .357sig caliber.

    Hornady already offers a 147-grain XTP in .357sig which gives 16" penetration but not quite 1.5X expansion. Maybe good for woods carry but not optimum for self-defense against human aggressors. And they also offer a 124-grain XTP that is essentially a 9mm bullet design as I suspect is the heavier one.

    Double Tap used to offer a 147-grain Gold Dot (I still have a couple of mags worth) but the company's published stats have come under considerable criticism so I'm currently sticking to my 125-grain Speer and HST rounds, with yet-to-function-test Golden Saber Bonded waiting in the wings.

    Once I get a chrono I want to see how fast I can push some 147gr XTPs to see how they do. I figure I may be able to get to get pretty close 1300fps. The Hornady 147gr sig loads are pretty watered down. All the XTP bullets have a good profile for the .357sig. The 147 GD is mediocre, don't know about the 147 HST but the GS 147 is a no go due to that stupid low driving band, it is strictly for 9mm.

    This load is the only DT ammo I've ever chronographed that actually exceeded box velocity. Out of my G23/32, it averaged a little over 1600 fps.

    Personally I believe penetration numbers to be amazingly academic... I could be wrong, but I'm quite sure the sorry individual who gets hit with that 115 +p+ @ 1400 fps is going to be one very devastated person...

    Based on what you're saying 135 gr 10 mm would be insufficient for self defense... I've seen it shot into wet packs... They basically exploded :supergrin:

    Tell that to the FBI.

    If the bullet does not penetrate enough to reach the vitals it really is not that effective. Unless you can wait long enough for a large shallow wound to get infected, cause sepsis and ultimately death.:dunno:

    Yes, I think that the reported 9 inches of penetration might be better for
    someone who doesn't want the 13+ inches of the SPEER or DT 125 gr. Gold Dots.

    That 9" was from the 115gr GD traveling at 1400fps. Push it to 1600fps I bet you will be lucky to get 7".

    Yep.

    These light weight speed freaks need a reality check.

    You are not hunting varmits.

    People have sternums, ribs, skulls, arms, hands ect. that may engage your bullet before it gets deep into the target. if a round only penetrates 7 inches in jello, try getting it to go through an arm (with bone) and then through a sternum then a half a foot through the vitals.

    Over-penetration should not be a consideration.

    Because if you ask people who actually USED these against humans they will tell you that they work like the Hammer of Thor, e.g., Fed. BPLE & Win. RA9115HP+. The problem is that these have been for the most part out of the mainstream for approx. two decades and the people who used them are retired. That, coupled with the fact that when they were in common usage there were no Internet sales and they were very tighly controlled with few in the public knowing little if anything about them. Administrators, being what they are, "administrated" into the .40 S&W as they believed all the FBI dog & pony show BS that in essence was a mere smokescreen for the fact that the FBI is really run by accountants and are involved in relatively few gunfights at all.

    Like every generation, the wheel has to be reinvented.

    When fired into the same media as all 3 Underwood 9mm +P+ loads the 9BPLE managed a little over 13" of penetration. I would say that the 9BPLE has adequate penetration. One can argue how accurate the denim/simtest media is compared to a body all they want however it does give a good comparison of what each cartridge is capable of in identical media.

    FBI requirements I'm sure have little to do with true Civilain self defense shootings at short distances... Guess I could be wrong but hey...

    I have an idea...stand in front of a 115 +p+ and see what happens.. Hell even cover yourself with 4 layers of denim... I'm going to go on record that you'd be gone LONG before infection or sepsis... I'm guessing more like 15-20 seconds :upeyes:

    I was referring to the lesson learned, not the bullet.
