Dynamic Research Technology 105 grain bullet.

I have playing around with the Dynamic Research Technology bullets in my 10mm. I have a real nice custom Reeder "Texas Ranger" series commander in 10mm. I also have model 20 Glock SF with a LW long slide atop.

The DRT bullets are a compressed copper core with a jacket hollow point. The site states the bullets are designed to penetrate till they tech organic material where the jacket will peel back and a spray of compressed metal will do total and immediate disruption of said organic material. 

The Videos are very impressive as are gelitin tests. You can google the DRT ammo or "Dynamic Research Technologies".

I did some wet news print testing and will attest to the fact fact that the gullets does devastating damage 2" in then the wad cutter base penetrated a total of 16" with straight wound track.

I loaded the 105 over Longshot and CCI primer and Starline brass.

From my Commander length barrle the bullet was running an average of 1575 FPS it ran close to 1800 FPS from my 6" LW upper.

Accuracy was outstanding with tight groups. The brass would clear my commander out to about 10 feet. The brass looked great primers well rounded on the edges and recoil was very very controllable. The bullets fed flawlessly in the Commander I had one stove pipe in the LW. So far I have run a 100 rnds of these. The performance in comparison to the XTP and hard cast HP was just as good and in some ways better with regards to the disruption of the news print after about 2-3" of penetration. I am looking forward to using these on game soon.

Yes I did a pull-down of one, what was found can be viewed here;

It didn't appear to be a compressed copper core though, more like a very light aluminum core wrapped by copper jacket.

Did you see any of the frag dust from the compressed copper core?

Here is the news print the hole you see is after 3" of penetration after initial contact. the base of the bullet penetrated a total of 16"

Interesting if you look at the "shock wave" around the hole shows the total transfer of energy very well.

I cut one and put copper bore cleaner on it tuned a blue color that would signify copper maybe? Aluminum may not be the worse thing if it is the harder alloy it may be why it penetrates then decompressed?
