I might be starting pure barrier penetration testing in the near future, in addition to the regular gelatin stuff.
Basically, I like the Box-o-truth stuff quite a bit, but some of the results are not telling me what I would like to know, and there are a few cartridges that I would like to test. To keep the results general, I'm not posting anything like the impact velocities or the uncertainty magnitudes (the '+/-' that appears on www.brassfetcher.com) - because I don't feel that every piece of, say drywall, will be as 'tough' as the next piece, etc. so these numbers are not as important as with the gelatin.
I tested a 18" barrel .22lr rifle against the FBI test #4 fixture (interior wall - 2 pieces of 1/2 inch drywall in 12x12" panels) with the CCI rat shot and the CCI Quik-Shok cartridges. 4" behind the panels sat a filled 3 gallon water jug.
The rat shot was fired from 3 feet from the muzzle, penetrated the first panel and indented the paper face of the second panel. No penetration into second panel was noted.
The CCI Quik-Shok, on the other hand. This round appeared to have fragmented upon impact with the face of the first panel. A ~ 3/8" diameter hole then followed the path of the bullet, with a 1/2" hole being present in the second panel. The water jug had a 5/8" entrance hole and 8" of penetration through 70 degree F water.
Any rat shooters out there with experience with this round?
