    'drsjr1969' Thanks for the results.

    Re: calibrating your Glock - Buffalo Bore rates the 220gr hardcast at 1140 ft/s from a Glock 20. So, your results are reasonably close.

    (Row 17 of the spreadsheet might need updating to that 1140 number.)

    50k PSI on the 9. Guess it is a good thing it is Starline brass but it didn't show any pressure signs and the brass ejected just great looking very good.

    Well, i see i have plenty of low and mid powered 10mm ammo on hand.

    If i start carrying my 10mm again for ccw i will load it up with underwood.

    Dave, thanks for your efforts, i really appreciate them.

    You I think. Was just wondering if the muzzle blast might be causing a high reading.

    No it's at max length away and the blast isn't causing an issue. I have shot from .22LR up to the .44 Magnum over it at the same distance and no issues. Readings are pretty darn repeatable as I retest many of the rounds over and over running them with new test ammos.

    Hickock45 did a video with his 10mm Glock and Double Tap ammo. He could not hit squat with the DT because the bullet was exiting the barrel so fast it failed to catch the rifling of the Glock barrel. When he switched to a Lone Wolf barrel with standard rifling he got superb accuracy. So I can assume DT ammo is very hot or their bullets are inferior (which I don't believe for a moment).

    I'm not a huge fan of DT ammo for reasons I'll keep to myself, but Buffalo Bore ammo has been great in every caliber I've tested. It rocks. There is nothing wrong with Double Tap ammo but I personally think Buffalo Bore is better.

    Dave, thanks for your efforts.

    it seems DT has been putting out that lower than claimed stuff for a while now.....its consistant, but not where they claim it should be.


    anybody wanna trade for my stash of DT, Win STHP, Hornady, UMC Rem, CCI, for some Underwood? LOL.

    I would like to thank deadguy for the 10 DoubleTap 180gr Noslers he sent me for exchange! The second DoubleTap testing video from today is uploading. I had 10 perfect shots/readings and if I had to guess these are late edition DoubleTap. Here are the numbers:

    1285, 1220, 1263, 1279, 1230, 1235, 1200, 1253, 1252, 1297. 1251.4 FPS/625.77 LBS.


    Sure does look like a shift to me and no way will you get remotely close to these numbers out of a stock Glock 20 4.6" barrel.

    Not quite the claimed velocities but getting there. I'm content with this in my CCO until I get more Scottsdale.

    Thank you IC for taking the time to test these.

    Hey intercooler, are you still testing 357 mags, or are you through with them? I'm still trying to find a factory 158 load that hasn't been neutered.

    I'm still testing them and would love to find a good 158. So far though I have found nothing. Kevin's 125 screams but his 158 wasn't all there. Maybe I'm expecting too much?


    Wonder who has the rep for a good 158? I'm willing to buy something for testing.

    Do we need a SAAMI standard for that?

    Adjustment!!!

    Well Mike is now rating the 10mm on a 5" barrel. That's closer to matching box spec's and if he finds another 1/2" in there somewhere it may get darn close!

    I haven't checked to see if he added 1/2" to all calibers but this is a step in the right direction! ;)

    I pretty much read this whole thread, but it still leaves the question unanswered as far as I can tell: At what point (year) did DT begin to decelerated their rounds?...Or were they always slower than advertised? Does anyone know?

    Who knows and who cares. Anytime you change things after the fact you end up with pie on your face.

    Better options exist for less $$$ these days.

    You would almost have to test a couple to figure it out.
