Glock 20 & Glock 29 - 9x25 Dillon Accuracy & Velocity - Lone Wolf Barrel - Underwood & Doubletap




What do you think about this video?

Vydonis: (It wont let me reply to posts) 10mm doesn't get the same fp/force the 9mm does. 6" barrel 9x25 underwood gets 1200joules of force. Highest I know of at 6" with a internal grip magazine. Upgrade to revolvers for higher joules. 10mm barely makes 1050 joules at a 8" barrel with underwood ammo.

UndergradPigeon: Those 125s would probably make a pretty sweet carry load, you know if you're the kind of guy that wants to make an impression on the threat and deafen everyone around including yourself Haha

Ammo Test: I am not sure on that one. I bought a box once and while it would run so so in my lone wolf barrel it would not chamber in my barsto 9x25 (the only rd that has not chambered in the barsto barrel. If it helps I kept the velocity data on it - 3.8" G29 LWD = 1819, 1808, 1825, 1800, 1810 6" LWD - 2077 2055 2043 2091 2071 Personally I'd like to see them load the 95gr or 115 barnes instead. ...just my opinion of course.

Beltfedshooters: Did you have to change out the recoil spring to a heavier one on the Glock 29? So far hows the reliability been on the Double Tap stuff running through your Glocks? Great vid!

paper000000: How much change did you have in your pocket?

jeremy67A: Great video! I shot some Doubletap ammo last week, I knew it felt a little weak! Your data confirms my analysis. Thanks a lot! I'll load my own in the future.

Ammo Test: probably just plastic lol

Zachary Geiwitz: there is already a .357 automag so they probably dont want any confusion

Julian Sears: I love my G20SF, so versatile, 4 different cartriges, bullet weights from 90gr-230gr, velocities from the low 1000fps range up to over 2000fps+. I don't know of any other gun that can do all of that with nothing but a berral change.

AJDrac: 45-70 - particularly the Marlin 1895. Anything from 250gr @ 2500fps to 540gr @ 1200, with no barrel change and A LOT of variety in between. Not a handgun however (though Magnum Research makes one - no thanks say my wrists).

tKoMaDClowN: Try loading Hornady XTP's 90 grain. Using Blue Dot, i get 2100+FPS from a 6 inch Lone Wolf. Fun to shoot.

Ammo Test: Yeah when I start my new channel I'll do just that and add it on to this vid. But 9x25 is more of a muzzle Blast than a recoil in my opinion. I must say that underwood's 357sig gets darn close to 9x25 velocities.

Zachary Geiwitz: It would be awesome to see this in a carbine of some sort like an AR or even a single shot

Ammo Test: haha especially with the G29 3.8" barrel version

Ammo Test: yeah pretty disappointed in double tap lately. They seem to be falling short on everything. Used them for years. The Underwood stuff was about half the cost of double tap

Tactical Training Group: thanks for that info and the great video

109268: And as Ric Romero reports, Double Tap and Buffalo Bore are caught fudging numbers harder than Ken Ley at the annual Enron meet in hell.

Ammo Test: I don't reload. but that sounds like a fun setup.

UndergradPigeon: How loud is the 9x25? I've heard it's pretty crazy loud and the blast is pretty ridiculous

Ammo Test: added links to underwood and doubletap in the description. I guess I can't post a link in a comment. Hope that helps.

jeremy67A: I'd love to have an MPK with a barrel just long enough to squeeze every bit of velocity out of that 9x25mm

Julian Sears: Yup my G20SF has a little slop, whereas my G19 doesn't, or at least its so little its unnoticeable. My Dad's friend's Gen1 G21 has about the same slop as my Gen3 G20SF, I think its normal for the Large frame Glocks to have a little more slop than the smaller frames.

Lorem Ipsum: MrRedbull. These videos are outstanding. I would love to see you test the 80 grain barnes 9x25 offered by Doubletap.

Ammo Test: Sir, there is some play on both my G29 and G20 but not much.

MustangDennis: Do you have any "play" in the rear of your G29 slide? The slide to frame fit of my G29 is loose and I can physically move it from side to side a few millimeters or so to the right/left over the rear slide rails. My G23 doesn't do that, so I was just wondering if that was normal for the bigger glocks. Thanks

Tactical Training Group: what was the temp the day of the test?

Julian Sears: Agreed, except that its still one cartridge (just different loadings), the G20 allows for 4 different cartridges, as well as all the different loadings for each. I like 45-70, I don't own anything that fires it, but would like to get my hands on a Sharps some day. I too agree 45-70 in a hand gun is a wrist killer...no thanks!

Ammo Test: me too! Both DT and UW are using 357sig bullets - 125gr gold dot. (9mm = 124gr)

intercooler2: I think you still have the links in the wrong place.

Breathin' Slow: other than using a conversion barrel, did you use a different RSA? if so what spring weight?

Ammo Test: oh man it's fun! Especially at distance. Point and Click! felt recoil is for sure less than 10mm.

AJDrac: I practically drool over any Sharps I see even after finally getting my Marlin. Apparently I'm just addicted to guns that I don't yet have...not sure if there is a cure for that.

Ammo Test: Looking at the 135gr 10mm different barrels video that I did ...I see the 135 out of a 6.61" LS threaded 10mm barrel I got 1737 with the 135. So I guess if you sliced it down to 6.00" like the 9x25 barrel is, they'd probably be almost identical. (6" 9x25 Underwood 125 avg 1699) Both barrels are lone wolf. All that said - I agree with you ...seems like the 9x25 should/could push it faster?

bobby m: I'm surprised that there is another distributor that sells the 9x25 Dillon cartridge other than DoubleTap. Thanks

bobby m: Where do you buy the Underwood ammo from?

Julian Sears: My list of guns on my "would like to own" list is so long its almost overwhelming, and I already own quite a lot. Last year I was up against the 1 new handgun per month rule in CA just about every month. I managed to find a new SAA in that time, which I promptly snatched up. You might say I have the same addiction! America needs more gun owners,

Ammo Test: I run a 23lb wolff spring and guide rod setup. Works for everything 10mm 9x25, 40sw and 357sig. (a little much for 357sig but it still gets the job done). I've had a few problems with DoubleTap not to many. Main problem has been on every caliber it's running slower than what the box says.

Carl Spackler: should call it the .357 magnum auto or the sig magnum

Ammo Test: probably around 80

Richard B: Underwood is the best value and performance of any ammo manufacturer out there. I will keep buying there stuff time and time again so long as they keep the same value and don't get all elitist on us like Double Tap and Buffalo Bore. Anyways, I look forward to your future videos here. Will your new channel be under the same name?

Alex K.: Don't see a point to use the 9x25 as a carry round, would stick with 10mm.

Shouldofstayedinbed: Im going with Underwood from now on. thanks

Richard B: You have created a great resource with your channel. I chose 2 new Glocks based on our videos (G33 Gen4, G32 Gen4, G20 Gen4). I would love to see a recoil demonstration of your G29 and G20 loaded with some Underwood 9x25 Dillon as I'm considering adding both configurations to my arsenal. Does the 9x25 have more recoil than 10mm??

jason murphy: another awesome video. this is a interesting round that you dont hear much about, but is super hot. what do you think the penetration is on this round, and do you think the bullet holds up?

paper000000: I'll look forward to that. I'm curios about the 9x25 recoil. Thanks for doing these chrono tests with real world barrels, well except for the 6". I'm surprised that it took the 6" to get the advertised velocity for the Underwood but not surprised the the UW came out on top.

Ammo Test: I'll put out a video with link to new channel once it's ready. Will be called AmmoTest

Alec Johnson: How is the felt recoil with the Dillon? I have been thinking about getting a barrel for my G20.

Ammo Test: I'd like to know!!!

beardown555: Awesome video! It seems that Underwood Ammo is true to their velocity claims. Thank you for your time.

tKoMaDClowN: Man reloading is fun. I get a lot of satisfaction knowing the rounds I'm firing i reloaded myself. When you buy ammo, you get what you get. Best part about reloading is all the different powders and bullets that you can use that you won't find in a factory round. Should definitely consider it if the possibility arises.

Schools: Learn how to get phlebotomy training in California! The job pays decent money for the amount of schools needed to graduate.
