I happened to find the site in the link where they test alot of different bullets in ballistic gellatin for penetration, expansion, etc. They only tested one muzz bullet though, a 50 cal Barnes. It would be cool to see all of the favorite muzz bullets fired into the gel at smokeless velocities to see how they perform. That might answer alot of questions about terminal performance on game.

Looks like the Barnes was up to the challenge

The "Lefthand"(mark) ran many of our bullet throught the test gel. That info is here somewhere...

Lefthand used PermaGel which is different from ballistic gelatin.
Brassfetcher does a pretty decent test. One of the "Tricks of the trade" is to leave out the calibration data. Since the gelatin is often recycled it varies. Block temp is another way to "fudge" the test. They should give you a block core temp after the shot (I think the DoJ and DoD now require that). You do your calibration shot with the block at 37-39° then set the block up under the lights to warm it up so the shot looks real good.
$125 a shot is cheap, a full round of the FBI test which is 8 tests, 5 shots each (40 shots) and new material must be used for each shot. Then another 40 shots for accuracy and velocity, 20 shots from a test barrel and 20 from a service weapon. The bill on that can run $40,000 easy.

I wonder how much gel you have to use to stop the Barnes 400 Buster bullet at 2147FPS
Lot and Lots and Lots
