    I hope this doesn't get moved to caliber corner,
    as it's intended for .357 Glockers and others who adore the round.


    An assortment of .357 SIG loads from Mike at Double Tap Ammo-
    arrived over the weekend.

    While I do plan to test them next week, I thought some photos were in order.


    I can only post 6 images, so i hope you like what you see.

    To begin with:

    The classic 125 gr JHP as loaded by DT with the Sierra bullet@ 1,450 fps
    from a 4.5 inch barrel.

    I believe this is the same bullet and velocity in Cor-Bon 125s, and the
    125 gr. weight is the gold standard of measurement for stopping power with the .357 SIG.

    Larger Pic: TAP 357 SIG/DT-357-LONGH.jpg

    Next up, we have the 115 grain Barnes TAC-XP as loaded by DT@1,450 fps.
    Same weight and bullet used in the street and cww proven Cor-Bon DPX.

    The newest Double Tap TAC-XP load is the 80 grain Barnes X bullet at a smoking 1,600 fps in 3.5" barrel ,
    and screaming azz 1755 fps for the 4.5 inch barrel

    I carry the TAC-XP lightweights in both .38+P and .380 and like what I've seen so far. Mild recoil with superb accuracy.

    Lastly, the is the 147 grain FMJ-Flat Point load.
    This is moslty intended for practice, but would be good for someone looking for deep penetration from the 9mm or .357 SIG.

    There are some people who workship 147 gr. loads, but I'm not one of them
    quite yet, even though I've only trusted the Double Tap 147 gr. +P load
    in 9mm to carry for protection.

    Velocity is listed for the .357 SIG FMJ-FP load is:

    3.5" barrel - 1213fps / 480 ft/lbs
    4.0" barrel - 1255fps / 514 ft/lbs
    4.5" barrel - 1296fps / 550 ft/lbs

    Quite a step over the subsonic 9mm for sure!

    I think that once a person decides to buy Double Tap,
    they will have quite a dilema:

    The tried and true/very traditional JHPs or the newer technology TAC-XP?

    I think both decisions would be winners!

    Please visit my photo albums for more pics, and
    Double Tap Ammo for more information.

  2. Nice looking rounds. Something about that bottleneck screams business :)

    I've always felt confident with .357 Magnum power, but prefer autos for carry.
    Wished for a .357 CZ for quite a few years now.

    Problem is, the custom guns in .357 are expensive and not small enough for
    ankle carry like the G33.

    So. Central US
    I've never shot 147-grain ammo through any 9mm pistol I've owned because I prefer the light-to-medium weight bullets traveling at a good velocity. I've always thought .357sig is the perfect caliber for the 147-grain bullet.

    There are more than a few Glock Talk members who have run Double Tap through their chronometers and report that velocity figures given by the company are exaggerated. I can't confirm or refute the claims of either side.

    I hadn't shot the Double Tap ammo I'd purchased in 2007 for some time until a couple of weekends past. The ammo I have in both 125- and 147-grain is the Gold Dot variety, when Double Tap used that bullet in its JHP ammo. The 147-grain was noticeably milder than the 125-grain DT Gold Dot and the other 125-grain ammo I was firing that day. I decided that's what I'll be carrying for the time being, and my next project is to compare the old 147-grain DT Gold Dots with some Hornady 147-grain XTP ammo I have but haven't yet tried.

    In shooting the 147 gr. FMJ-FP load on Saturday.

    I found it to have less recoil and muzzle jump than the other 357 loads.

    Muzzle blast was still there but that's the fun of the 357 SIG.

    It also printed a nice little groups for me.

    Even with the Glock 33's short barrel, you are still geting over 100 fps more
    out of the load than a comparable sub-sonic 9mm 147.

    3.5" barrel - 1213fps / 480 ft/lbs DT published velocity.

    I don't know if you get that 357 SIG 'pressure wave' that people talk about
    with the higher velocity loads, or not.

    In reality, it seems that from real world shootings, and internet testing of course.

    The 357 auto is like the .270 Winchester.

    It pushes the envelope for performance, and works far better than it should.

    I think the sleeper load is the 80 grain Barnes bullet at 1755fps

    It kind of reminds me of the .30 Mauser or CZ52 cartridge in concept.
    Chinese and other gangsteers of the 20's and 30's were petrified of getting hit
    with a Broomhandle round, as they could lose a limb due to the hyper velocity
    wounding effect.

    The DT round has low recoil but quite a bark to it.

    I hope to get out and shoot some more next week before the snow arrives.

    Know that unlike my old G26, the G33 didn't feel like it was going to jump out of
    my hands with any load I shot through it.

    More of a straight back, brisk recoil with little muzzle jump or moving around 'in my hand.

    A my book!
