    I imagine its not too much of a problem with a longer barrel.

    Personally, I have run the 135 nosler all the way up to 1834 fps and that figures in at over 1000 fpe.

    That was out of a 4.45" barrel ---> longer barrels = higher velocity yet.

    Agree w/ Kegs.

    But thanks for the effort and the link - cool stuff ... :cool:

    Tough crowd to please you guys that roll your own

    Maybe I should have said 1200 ft lbs of energy .…… true story.

    No, seriously, I appreciate all the 10Ringers who take the time to do this sort of researching, testing and load-development on our favorite cartridge, and then help the rest of us by posting or linking to the results! :thumbsup:

    :)

    Interesting. I would have liked to see Double Tap also shown in this side by side. DT has taken criticism for publishing velocities faster than reality. A side-by-side comparison to published vs real velocities on the same day, same elevation, same temp and same chronograph would give a nice comparative of the claims made by the various companies.

    Thanks for the visual reports DRSJR1969, I posted on your facebook about the smiled brass.

    Nice. There has been a lot of buzz about that Mech Tech setup. Tempting.

    2000fps with factory ammo out of a carbine using a pistol round is a significant achievement. that is 30 carbine territory and would yield some pretty significant terminal ballistics if the bullet would hold together.

    I cant wait to see what I can do with some 125gr gas checked SWC's

    I think 2000 FPS should be reasonably easy to do with my 5.2" barrel+comp, depending upon if I can get a proper alloy to prevent the bullet from self destructing in the barrel.

    'drsjr1969', even the 6" barrel was impressive.

    "Ultimate video" sounds like it might be the "last one". But, you've tested just about all the 10mm rounds out there. Thanks for your series of videos.

    It made sense to pass on DT for the Ultimate Test. I don't know if pressure from Swampfox and Underwood has made them up their game, but based on 'drsjr1969' videos, speeds appear to have dropped about three years ago.

    I suspect 'intercooler' is not a member here, but he recently videoed and recorded the speeds of some older Double Tap 10mm ammo.

    2005-2007 era Double Tap 10mm ammo chronograph results:
    http://www.thehighroad.org/showthread.php?t=652805&page=7

    I have a bunch of DT ammo from that time frame and provided some for testing. Performance was close to spec with those older rounds.

    I noticed the first round out of the Mechtech was lower velocity than the others with each batch of ammo - something going on there, but not sure what?

    Gofastman, you'll need some seriously hard cast bullets, and very careful lube selection, for that kind of velocity without significant leading. You can do it with heat treated wheel weight alloy, but expect to be cleaning the bore often. I assume you're using some commercial cast bullet though? Where are you getting them? The common commercial casting alloy should be up to the task, but the lube may not be.

    I've seen 1680 fps with my cast 160gr hollow points (1,000 ft-lb) from my 6.6" compensated long slide, but those loads were a bit hot for the LW barrel. Would probably be OK in a KKM or similar. I'd like to see what that would do in the MechTech.

    Some penetration comparisons would be great as well.

    Im getting a Ballisti-Cast #965 mold. Im going to be using soda can gas checks (kind of like the ones you make) on them.

    I'm using that new TAC#1 stuff spoke with you about in a few PM's I sent. unfortunately I haven't had a chance to shoot any of it yet.

    The alloy I use is mostly wheel weights with some Antimony and Tin added, it should be similar to Lyman #2 but with a trace of Arsenic in it. I would imagine with heat treating a BHN of around 30 wouldnt be out of the question :wow:

    I am interested in the "relative" accuracy at 15 yrds, 25yrds, and may be just accuracy at 50yrds.

    Relative as in compared to a stock G20 at 15 and 25 yrds.

    Thx.

    If accuracy looks better, I'd be inclined to spend $500 with MechTech than a Gen4 10mm gun.

    I'm also interested its chamber support, a close up picture of it.

    You're getting to be a salesman for MechTech.

    I'm really interested to hear about your results. Maybe we'll have to do a bullet swap at some point.

    Those 16" IGB barrels look pretty cool. Looks like there are ports in the barrel though, so you'd want to keep that in mind when shooting cast bullets. They should be OK with a gas check of some sort, but plain base cast bullets will suffer from uneven gas cutting of the base as the bullet passes the ports, which is usually bad for accuracy.

    They do looks expensive though. You should buy one, and report back. :supergrin:

    I wonder what one of my hot 135 grainers would do through a mec tech. 2200 fps maybe?

    I wish the mec tech people would make their unit fit the G29, because I have no interest in purchasing a G20.

    The problem with getting mega energy from a handgun cartridge is that the ballistic coefficient of handgun bullets suck.

    You would still be stuck with a massive drop out past 150y.

    A .22LR has a flatter trajectory than a 135gr. nosler @ 2200fps...

    .40 is okay for a rifle so long as you make the bullet about 4x longer than a 135 nosler. :supergrin:
