Adams Arms 7.5 PDW gel test with GD and TBBC (gel data added)

So where does that place the Winchester load that the FBI approved at the same time as the TBBC?

It is too bad there seem to be no cheap bullets which are good for barriers followed by soft targets.

I see in that link you have a list of decent barrier loads, and the Remington Core-Lokt ultrabonded is listed along with the 223 version of the TBBC.

How does the Remington 62 grain bonded fit into the Gold Dot vs TBBC range vs Mk318?

How much better, if any, is the Barnes 50 TSX compared to the Remington 62 bonded?

If you don't mind me asking, what medium were you firing these projectiles into? What were the penetration depths?

Impressive projectile performance regardless though.

There is some info here: https://www.m4carbine.net/showthread.php?t=26127&page=2

I'd put the Rem Core-Lokt above the Gold Dot and below the TBBC--probably on par with the TSX, although it is hard to accurately compare given the different pressues..

These two were just straight ballistic gelatin.

They also fired them through the common barriers during the testing - glass, drywall and some clothing I believe. I wasn't there for that part of the test. I got there right before they tore down and had em shoot those two rds for me. They both penetrated @ 17-18". I'll try to get the pictures from the rest of the testing and the data to go with it and pass it on.

Once again, simply curious, but was it properly calibrated BG?

I am eager to see some data with intermediate barriers.

ETA: OK I understand the context now. I would assume it must have been for such testing. It is impressive to see these results from an 7.5" AR.
