There has been much speculation about the new DRT projectiles. As noted in previous threads, DRT (http://www.drtammo.com) appears to be producing the same type of powdered metal projectiles previously made by Powell River Labs and used by some U.S. units in the late 1990's. The PRL 5.56 mm and 7.62x51 mm rounds offered superb accuracy and terminal performance, however PRL had some production and QC difficulties. Dr. Fackler presented a paper in the IWBA Journal discussing the 5.56 mm 76 gr PRL tungsten-tin core rifle projectiles: Fackler, ML: "Tungsten Frangible Bullet Wounds in Pig: Exam by Autopsy and X-Ray". Wound Ballistic Review (4)3:33-34 Spring 2000. We independently tested the 61 and 87 gr versions of the PRL bullet at the CHP Academy in late 1999 and had similar results. Ironically, the PRL/DRT bullets are true "Blended Metal" projectiles...
Like the 61 gr, the current 79 gr DRT ammo is a bit deficient in penetration; it would be great if they started building the 87 gr version again...
