The reason I won't go negative on Double Tap is because they are the best thing going for 10MM fans and I appreciate that.

this is quite true. very few companies are making an effort to produce 10mm rounds at 10mm power levels, regardless of bullet design. Cor-bon makes a nice 10mm round though its not loaded much hotter than thier .40cal round. Georgia Arms makes a nice 10mm round but its still only a "warm" load.

Buffalo Bore makes some hot 10mm rounds but the price is high compared to others. Double Tap makes 10mm powered loads, though the bullets used might not be the best for the speeds they are loaded to. but they are making the effort, and i like that.

Hey .380 ACP fans!

I heard back form Mike today and got some penetration results on the .380 loads!

90gr GDHP - 9.5" .53"
95gr JHP - 11.25" .47"

The "JHP" is his newer "XTP JHP" load. The GDHP is his earlier load that does o.k., but is outperformed by the CorBon DPX, for example.

That XTP JHP looks like a winner to me, though- Competitive performance, more reasonably priced- Doubletap FTW!

Those numbers are out of a P3AT, by the way.

Over on M4C.net an independent test of DT's 40 S&W 155gr GD load provided an eye opener.

.40 S&W Speer 155 gr Gold Dot JHP; ave vel=1166 fps (S&W 4006); gel cal= 9.5cm@ 585fps
BG: pen=13.2", RD=0.64", RL=0.32", RW=155.5 gr
4 layers denim: pen=16.0", RD=0.60", RL=0.44", RW=155.3gr

.40 S&W Double Tap 155 gr Gold Dot JHP; ave vel=1208 fps (S&W 4006); gel cal=10cm@578fps
BG: pen=15.0", RD=0.66", RL=0.39", RW=155.6gr
4 layer denim: pen=17.1", RD=0.55", RL=0.42", RW=155.2gr

RD=Recovered Diameter
RL=Recovered Length
RW=Recovered Weight

Far cry from DT's internal claimed .76" expansion. I would like to know how they measured the .76 expansion.

I'm not concerned about over penetration?

I too would like to know. Thanks!

10mm 155gr. Barnes TAC-XP Data? Thanks for great ammo, Mike!

Mike, thank you for this information. You offer excellent ammunition and a great service. Ive ordered 10mm ammo and 45 acp ammo from you on several occasions and have never been let down. Thank you.

[hunt_ak]

Any chance on penetration tests on the hardcast loads, Mike?

[roach4047]

165gr Gold Dot JHP @ 1400fps - 14.25" / 1.02"


1.02" expansion measurement. That is amazing. This round is a freak of nature.

No????

I'm assuming the hardcast loads have to be good sellers. I know the data would be much appreciated to the Alaska/Anyone carrying a 10mm for 'tooth and claw' protection...

[firemedic1343]

I'm very curious. I would love to see testing done on some 10mm hardcast

[Dr.Og]

another vote for hardcast 10mm data. it would be nice to have it. i am about to buy a bunch of these rounds.

[ennis]

The data for the hardcast penetration in Ballistic Gel or wet pack paper/phonebooks would be interesting, but something closer to Todd Corder/John Linebaugh's "bone box" would be more on the mark for what I'm looking at in performance from the Double Tap hardcast 10mm.

Excellent information. It helped me decide what I plan on using for my purposes.

See my last post on the thread Glock2020.

that is the best performance I have ever seen out of any auto pistol. Does anyone know if outside testing ever colaborated these results..

Still they are awsome

[SolidBrass]

It doesn't say if those speeds are chono'd. I'm guessing that they were not and taken from the box. DT chrono videos on youtube show they are a good 10+% weaker the box lists. The gel depth is impressive for sure, I just wonder what they would do with velocity numbers that were truthful. (AKA Swamp Fox and Underwood)

[Chris Miller]

Very good info to have. Thanks a lot for taking the time and making this available to all of us out here! Very cool of you...

[Andrew Wiggin]

I presume McNett has never bothered to respond to questions about the accuracy of his claims. This "data" would be really interesting if it were to be believed.

He won't address the ridiculous inaccuracies in his advertised velocities. Still wondering why this is push pinned...

I use the 200 grain XTP with 13.0 grains of AA#9. Average velocity is 1113 with s=7.3. I gave trying to get to 1200fps for various reasons. Pressures were getting to the edge. If I need more power the 44 Mag is pressed into service.

I chronoed on 25 Sept 2012 10 rounds from 13 May 2004, lot number, 000079, the 200grain XTP. I got an average for 10 rounds of 1163 fps with s= 16.53

Not 1250 but good enough for me. I suspect that getting 1250 out of the short Glock 20 barrell may be pushing pressures to the line. Next project is getting the 6 inch Barstow barrell.

Short?

That's a full size pistol.

What length barrel are they using for their numbers?

[Slateman]

So is the OP still good? Or is it out of date?

[Warp]

I certainly wouldn't buy anything from DT and expect performance such as what was tested 7+ years ago.

But then gelatin results aren't the whole story anyway, even when they are currently relevant.
