DoubleTap .45's
 

Just got a couple of boxes of 230 gr. for my G30. They fed without a problem and felt a bit hotter than standard 230's. As far as the chrono #'s DT claims, has anyone come close to their numbers?

I have never shot the DT 45 acp JHP loads. The 230 grain DT TMJ ball loads run good in my Glock 36. Not sure how fast they are in my Glock but they penetrate better in wood than most other ball loads. When I do take the 36 on walks it is usually loaded with two Hornady 230 grain TAP +P followed by five of the DT 230 grain ball loads.

I have never reached the adverised velocity with DT. Can be good ammo though. The last one I checked was a 40 S&W load. 135gr. Nosler, which was advertised to be 1,375fps out of a 4" gun, but I could not get above 1,325fps. It could be my gun, but the 135gr Corbon advertises 1,325fps and that is pretty much what I get out of the same gun.

I have not chronographed the 45 230gr. in a 5" barrel, but I find it hard to believe they reach 1,025fps without being at least +P and they are not rated so.

I have chron'ed the 45ACP 185 jhp out of glock 21 and 1911 with 5 inch barrel

out of the glock 4.6 inch barrel 10 shot ave. 1119 fps
out of colt 1911 5 inch barrel 10 shot ave 1128 fps

the box says 1225 out of 5 inch 1911.

hope this helps

I shot the DT 230 grain fmjfp over a chrony from a stock G21sf: 843 fps.

DT 230 grain GDHP gave 909 fps.

I wonder if they have changed the load. These numbers are closer to the Federal American Eagle and Hydra Shok standard loadings. The 230 DT ball I have in my ammo box has always seemed a little hotter than most ball loadings except the Buffalo Bore 230 Flat Point.

I don't know. My past orders of 10mm ammo was acceptably close to DT's advertised velocities. Those orders were from around 2004. My 45 auto order was from 2007 and I just sent them over the chrony this past summer in 2009.

I was surprised about it myself. The DT fmjfp in 45 auto has been my carry load when I go fishing. Now I'm looking to work up my own handloads for that purpose. I still like the GDHP load and IMO it does outperform the Speer loads I have used in the past.... at least as far as velocity and terminal performance on aggressive water jugs... ;)

Just finally got around to trying them a couple months ago. I have been shooting their 9mm stuff for a couple years and have been very happy with them.

I tested 2 loads. First is the DT 230gr FP ammo. Out of a G21 they gave me 875 fps. Out of a G30 they gave me 815 fps.

Second is the DT 230gr Gold Dot load. Out of a G21 they gave me 890 fps. Out of a G30 they gave me 860 fps.

I was not terribly impressed with the FN loads and my shorter barrels. My hand loads beat that. 815 fps in a G30 is a long way from 1010. In fairness though, that is for a 5" barrel. However, the Gold Dot load is simply the finest carry load I ever fired out of my G30. This is a personal opinion and not a professional one. In terms of velocity, recoil, slide velocity, fast shooting in either hand and reliability, this quickly became my carry load. Though the velocity is not stunning, a Gold Dot at 860 fps under full control out of a G30 is a wonderful thing.

Even if the DT 230 grain FMJFP is running in the standard velocity range it would still be a good pick for a field load. You may want to pick up a box of the Buffalo Bore 230 FMJFP +P to try out. They are a pretty hot load and I would bet closer to their advertised velocity of 950. In my own penetration testing the BB load offers the most penetration out of the 45 acp loads I have tested with the DT 230 grain ball running second. The Federal American Eagle 230 grain ball is not to far behind the DT. Real Guns tested the BB 230 FMJFP +P out in wet newsprint and got 30+ inches of penetration. Almost twice as much penetration as the 230 grain JHP loads. I was on the Speer LE site yesterday and noticed that Speer is loading a 230 grain TMJ flat point at standard velocity. A standard 230 grain FMJ load like the Federal American Eagle would not be a bad choice as a field load either.
