DRT AMMO Testing – Part 1

I have some interesting terminal performance testing and in the field results to share on the 223 Remington cartridge and DRT ammunition.

FIRST – It’s important that you understand that a 223 Remington will kill deer IF, just like with any cartridge, you hit them in the right spot, AND IF, you use a good bullet. My sons and I have killed many deer with the .223 Remington using Nosler Partitions, Barnes X Bullets and even the newer, Brock Lesnar touted Fusion bullet. WITH NO FAILURES I might add. I even used a 223 and Nosler Partitions on a bushbuck in Africa and the PH’s son shot a mature warthog with the same. Based on my field experience and testing in various mediums a .223 Remington with correct ammunition is as effective as a .30-30 Winchester.

SECOND – Before I get into that what I saw today, some technical information on the ammunition needs provided AND it needs broken down to HILLBILLY simple.

DRT ammunition uses a bullet built with a J4 jacket (This helps with accuracy because these jackets are so consistent – ever heard of Berger Bullets? They use J4 jackets.) Inside this jacket is a core that is made from very, very small particles of copper and tin that have been compressed with a six-ton press. This compression results in a block of material that is inserted into the jacket and then the ogive – nose of the bullet – is formed. Make sense?

When the bullet hits something like an animal this compressed core needs to meet an uncompressible medium – like the liquid inside an animal – to make it do work. The work that it does is equal to the work (the compression by the six-ton press) used to compress the particles. Essentially, it uncompresses VERY fast.

The result is the release of these many, many tiny particles of copper and tin into the animal. These particles are driven by the linear and rotational velocity of the bullet. They are like the little nanites from the movie, The Day the Earth Stood Still. They devour (shred) the tissues they come into contact with be they in the form of lung, heart or bone.

60 grain, .223 Remington DRT bullet in PermaGel. (About 10 inches) NOTE: Unlike 10% ordnance gelatin, PermaGel does not show the cracks that radiate out from the wound cavity like in 10% ordnance gelatin. What you see here is the crush cavity.

Enough of this technical kind of stuff. Just digest the information and forget about the logical bullet terms you are accustomed to like retained weight, expansion, traditional mushrooming and sectional density. It does not apply. This is new technology.

Does it work? Tomorrow the results.

    Any information on how you deal with the uncompressed particles in meat?…thanks…jim dodd

    Jim,

    Good point to bring up! Without writing a complete article, let me make a few comments:

    1. like the Berger VLD, these bullets penetrate two to three inches before coming apart. This keeps from seriously blood-shoting shoulder meat or filling it with bullet particles.

    2. If you put the bullet in the chest cavity, the organs are where the particles stay. Unless you like to eat the heart or liver, its a non issue.

    3. Here’s the deal, the core of this bullet is not 100% solid. It has about a 20% void. This void fills with fluid after jacket collapse and this fluid drives apart the particles. Essentially, it makes the water content of the critter work against it.

    4. The denser the tissue the more contained the damage. For example, one buck was gut shot and the wound was so violent the entry hole was as large as a baseball. This of course was due to the water content of the gut. Shoulder shot deer looked like they were shot with a VLD. You could almost not find the hole because of the delayed expansion (coming apart of the bullet.)

    5. I think if you treated the butchering process like you would with any other bullet wound, there would be no issue. However, never having butchered a deer shot with one of these bullets, that’s only a guess based on the autopsy of what has now been 16 whitetails.

    Finally, and I’ll say this later again in a post, I’m not saying this is the best hunting bullet ever made. What I am saying is that it works, even when impacting bone, because it damages SO much tissue, blood loss happens faster. The sooner the brain runs out of oxygen (blood) the sooner the animal dies.

    16 whitetails taken with 18 shots from a 223 stand as proof. Both that required a second shot were the result of bad shooting on the first shot.

    Looking forward to testing the bullet as well. The basic concept is time proven with the Glaser Safety Slug. I can see a HUGE law enforcement and Miltary interstest based on the merrits of its design. No ricochet and minimal overpenetration are key factors to be considered when dealing within the confines of a structure or within a area populated with civillians. As for the performance, I propose that some care must be given to the shot selection so as not to try to drive through bone with enough denisty so as to test the penetration limitations of the bullet. That said, under most conditions the DRT bullet appears to be cutting edge technology that brings the dimutive .223 onto the playing field of legitimate small rifle cartridges. How do I get my hands on some ammo to test???

  5. gunwriter says:

    J.D.,

    Yeah, it is similar in concept to the Glaser but very different in performance because of the delayed expansion and because of the how the core reacts to fluid based tissues. You need to contact Dustin Worrell with DRT. I spent a great deal of time talking to Dustin and he knows a lot about bullets. This comes from making them and using them to shoot a lot of deer. (He manages the preserve where we were shooting deer.) Dustin took the original design which used a tungsten core and converted it to a copper core. This makes the ammo MUCH more affordable.

    What is the 223 60 gr DRT’s bullet velocity in feet per second?

  8. Michael Saari says:

    As far as 223 firearms are concerned: Nothing works better for taking deer than the 60gr DRT bullet. (Period) I don’t recommend using the 79gr DRT unless the deer is beyond 300 meters. (Also confirmed by DRT representative) The 79 gr DRT’s are made out of a different material. (Actually titanium)
    DRT’s are all I will ever use from now on. When I opened my deer after using the 60gr DRT, (100 yard shot) there weren’t any lungs inside. It was all just mush… The deer just dropped straight down…
    DRT’s – All the way for deer.

  9. Jim Dodd says:

    RM,

    thanks for the reply to my earlier comment; does this design scale up to .30 cal?

    jim

  10. Michael Saari says:

    I believe the new DRT bullets are twice that of a 30-30. I’ve tracked deer hundreds of yards (Blood Trails) sometimes not even finding them. With the DRT, they just drop. (No more blood trails) To answer your questions does this design scale up to .30 cal?
    My Winchester 30-30 is for sale….
    -Michael

  11. Michael B. Saari says:

    The end of your first article on this page asks: Does it work? Tomorrow the results.
    I never read your results regarding this DRT bullet.
    Are you able to email me your results.
    I really like this bullet alot.
