Is this ammunition legitimate?

Neither Hodgdon, Alliant or Accurate publishes a load that is within 100 ft/sec of that velocity. Maybe they found a magic powder...
 
Yes, it is CLOSE to the ballistic listed, but keep in mind that velocity will change with gun ( barrel length) used, temperature, altitude and other factors so don't get hang up on the ballistics too much.

Pressure wise, it is CLOSE to +P load so make sure your weapon is +P rated

Maybe they found a magic powder...
they blend the powders for max performance with pressure kept within SAAMI limits
 
Would an ammo maker fudge velocity figures? Why that is unthinkable! It would be like a politician lying to us!

Back in 2007 I chronographed DT's 230gr Gold Dot loading at ~970fps from my SIG P220. Keep in mind two important caveats:
1) The SIG has a 4.4" barrel vs the 1911's 5"
2) My results were at ~500' MSL vs DT's 4000'+ MSL location.

I believe this http://www.doubletapammo.com/php/catalog/product_info.php?cPath=21_34&products_id=277
loading is similar to the older discontinued gold dot loading

So ya, I think they could push a 185gr bullet at 1200+ fps out of a 5" tube.
 
Maybe, maybe not, but there have been previous threads on various forums where DT's numbers were called "optimistic". The only way to tell is to try some in YOUR gun using a chronograph
 
It’s the best, biggest, fastest, longest lasting, etc. Advertisers will go to any lengths to sell a product. To justify their claims they will set up unbelievable scenarios and tests to prove them. These tests rarely resemble anything found in the real world. Caveat Emptor.
 
A 185 at 1200+ seems like a very strange .45 load. Where do you get a bullet intended for such velocities? That is, the bullets are designed to work within a certain window of velocities, but how does the bullet work when driven 100fps faster than that? I'd be especially suspicious of, say, a 180gr load in 10mm at 1300+fps; today's 180gr, .40" bullets are surely designed for use in .40 S&W, so driving them 300fps faster?

It depends on the bullet. Speer Gold Dots have an excellent reputation for resisting fragmentation due to their bonded design. In the tests I've seen, Gold Dots' petals will simply curl around the base of the bullet rather than fragment when driven at extremely high speeds. Similarly, Hornady XTP bullets are not a very aggressively expanding design and as such are well-suited to being driven at high velocities. Nearly every failure I've ever read about or seen with XTP's has been a result of driving them too slow rather than too fast.
 
I was reading a post somewhere from a guy who'd shot a deer with a saboted XTP in a muzzleloading rifle, driving the bullet a lot faster than any pistol, and the bullet performed well. The design of the XTP, in particular, does appear to work well at high(er) velocities.
 
Hhmmm...no, I know several people who have chrono'd DT's 10mm loads & 6.8 loads. All of them state that the measured velocity is considerably less than what DT claims. The misrepresentations of the hyped velocities were far greater than the "usual" manufacturers fps fudge-factor.--Patrice:cool:

A 300-400fps deviance is not very big. Most bullets are designed to expand within a velocity range that often spans as much as 1,000 fps. Some dual purpose bullets (pistol and rifle) are even designed to reliably expand with ranges that span nearly 2,000 fps.


Next time you're in a local shop that carries reloading books, pick up the Hornady reloading manual, and anything else that has the plastic removed.

You'll see pages and pages of charts telling you exactly what velocity range each bullet is designed to expand in.

That, of course, is the ideal velocity. In reality, things often differ.

One of the most popular low-cost bullets in factory ammunition in the U.S. is the Winchester Power Point. The very same bullet is produced in massive quantities for bulk sales to reloaders. In .277" diameter, the 130gr bullet is the most popular. I used to buy them when I found a good deal on a bag of 250-500. Last time I checked, they were rated to expand from 2,100-2,800 fps. (Pretty sad, considering they are coming out of the .270 Win at 3,010 fps, according to the label.)

I got tired of the crappy accuracy from the Power Points I had, and decided to load a bunch of my 130 grainers on top of some Trail Boss powder. At a whopping 1,200 fps, they still expanded.


And... for those of you that don't pay attention (some noticed)....
Double Tap lists their test firearm next to the velocity and energy figures.
