55 grain drt terminal shock load data?

I am trying to find load data for the drt terminal shock 55 grain bullet. I've been looking all over and can't find it. Any guesses?

If you don't post the chambering, nobody will have a clue what to tell you.

Contact DRT. They'll likely have suggestions: (660) 564-2331. Since their bullets are frangible, they are likely longer than standard 55 grain bullets, will therefore stick deeper into the case and so will need to be used with a little less powder. Without the chambering and bullet length, though, I won't try to guess how much less.

I find the idea of "DRT shock bullets" from any rifle amusing.

I just saw a episode of Midway's "Shooting Gallery" where he used- IIRC- a 55 grain bullet in an AR platform to show that- contrary to "myths" about over-penetration- that the 55 grain (5.56) round actually has less than many popular handgun rounds due to the fact that it becomes extremely unstable upon contact with a barrier. Can't recall whose bullet it was, though.

Tests were done at Gunsite with ballistics gel, but there was no hard data provided. Set your Tivo to record the series, it'll probably be back on again soon.

It's the probable explanation for why the Linebaugh institute found 500 grain Hornady RN Solids penetrated further from a .45-70 than from a .48 Win mag, which penetrated further than a .458 Lott. The faster they go, the more they yaw at impact, especially when fired up close and still not recovered from initial yaw after leaving the muzzle.

On pages 406 and 407 of Hatcher's Notebook are photos of damage done to oak by two identical 150 grain .30-06 rounds at two different ranges. The first impacted at 50 feet, and the other at 200 yards. The first one yawed and turned and penetrated 11.25 inches in the end, while the second penetrated 32.5 inches. So, the second one penetrated not quite three times further because it didn't yaw and made a straight line through the wood, despite striking the target going about 250 fps slower.
