Doubletap 9mm Barnes Tac-XP
 
Has anybody used this stuff before or heard anything good or bad about it? Im thinking about getting the 115 gr version for my larger handguns and getting the lighter 80 gr version for my Kahr PM9.

I would rather use the Corbon DPX ammo. And I would use the 115gr for both guns. The Barnes is a good performing bullet.

I dabbled with boutique specialty ammo as probably most have but finally realized that for the same expense I could find reliable and effective premium JHP self-defense ammo at half the cost. I know nothing about the Barnes bullets but I understand they're excellent.

The DT 115 gr. TAC-XP uses the identical Barnes XPB solide copper bullet as DPX.

Even loaded a little hotter.

Shoots very well through my guns and has low recoil with amazing accuracy.

I carry the 115 in my alloy RAMI, and the 80 gr. in my polymer RAMI P.

The only real drawback to the Barnes XPB is price.

Easily the best bullet design on the market.

Unlike HST and other bonded bullets, there is no jacket to shed,
or any lead at all.

The DPX has also shown to be a dynamic stopper in more than a few shootings.


Rated very highly for stopping power and excellent tactical penetration
in most tests, and by real world experts.

Do you have any evidence of the DPX performance in actual shootings? I have been looking for information and even Mas is only aware of one shooting that was the 40 S&W.

I carry the DT 45 ACP with the 160gr Barnes bullet in +p in my Kahr P45.

clarkstoncz 11-13-2012 17:14

The stopping power.net fprum guys swear by DPX.

I've read in the past that the 9mm DPX has worked well
in actual shootings.

I do know of one dynamic stop with the 125 Sierra
.357 SIG load from Cor-Bon.

Those guys love CB and swear by DPX, as do some real world Experts ..
out there.

You are carrying the exact load that I'd use in a .45 ACP
these days.

Have you run them through a chrony?

Half the price as, say, Underwood? For 50?

I ran a 10 shot string through a chronograph with a G17. (CorBon DPX 115gr load). Temp. was 91*F.

Avg. 1207 fps
E.S. 69 fps
Std. Dev. 19.57 fps.

Underwood is the exception for hyper velocity boutique ammo from what I can tell. Their prices are still competitive with the large ammo companies the last I checked. I haven't tried Underwood because I have a good stash of self-defense ammo, but if I'm in the market for more and prices are still reasonable I'll go for it based upon what I know at this moment in time.

And from all I know about Underwood it seems that in 9mm I'd go for the 124-grain Gold Dot +P, which from Underwood's published stats is loaded about the same as Speer's comparable round.

There are quite a lot of positive testimonials for the Winchester 127-grain +P+ so I suppose the Underwood 124-grain +P+ would appeal to those same folks. Not a lot of added oomph for me to select that over the proven Speer +P and a few other rounds.

That's a pretty anemic round if your stats are any reliable indication of the light Cor-Bon round through a G-17. I thought Cor-Bon was supposed to be a "hot" round, given that the Speer 115-grain standard pressure Gold Dot reliably produces that same velocity, as confirmed by tnoutdoors through his G-19.

Just taking a blind shot in the dark on this one, but it may have something to do with the fact that the Barnes 115 gr. copper bullet is much longer than your standard 115 gr. bullet, and as a result, the volume available for the powder is much less than a normal 115 gr. bullet. I've captured one of these rounds in a line of water jugs and it expanded to a decent size and had good penetration.

Please tell more about the 125gr 357sig Sierra round shooting. I sometimes carry this bullet from DT at 1,500fps out of my 4.5" barrel.

SCmasterblaster 11-14-2012 07:16

The Barnes is a promising load.

I was asking him about the DT ammo because I doubt you will see the advertised 1320 from them.

What was Corbon's advertised numbers for the 115grn?

SCmasterblaster 11-14-2012 14:12

The original CorBon 9mm 115gr JHP would chrono out of my G17 at a reliable 1350 FPS.

No. The blunt-tipped Sierra bullet. :cool:

One day I am going to get some of those Sierra bullets and reload them. But for now, I'll use the CorBon rounds.

Corbon hasn't used a Sierra bullet in their 9mm 115 gr. for years. They make their own proprietary bullet. They recently changed the design to give better penetration as well.

SCmasterblaster 11-16-2012 20:06

Thanks

I didn't know this. It sure looks like a Sierra bullet!

clarkstoncz 11-21-2012 14:15

I bought a few boxes of 125 gr. CB .357 SIG last year.

They look identical to the DT 125 gr. Sierras.
http://i204.photobucket.com/albums/b...DT-357-125.jpg
Whether or not CB has gone to a different design is unknown by me.

Although expensive, I still like my DT Barnes loads in all my current calibers that I use.
