This is an initial "proof of concept" test with the end goal being the ability to compare terminal effects of various rounds fired into Perma-Gel. I understand that Perma-Gel is not calibrated ordinance gelatin and that the best results would be obtained by firing rounds into separate blocks, but I think the proposed set up will be sufficient for general observations. Criticism and other recommendations is welcome.

Pictures of the gel
All shots from 10 yards through a 16 inch 1:9 barrel.
The bottom most track is the Hornady 55 grain TAP. Just above it (look carefully) is the track for the 55 grain Barnes TSX, which penetrated the gel but was recovered after bouncing off the wood backstop. The middle track is from a Federal XM223SP1 62gr Bonded round, notice the five petals. I found it interesting that it had similar penetration to the majority of the Hornady round. The track just below the top track was where the MK318MOD0 passed through. The MK318MOD0 is copper bullet with a non bonded lead pocket in the front half of the round. I've found that the front half of the MK318MOD0 has a tendency to fragment and the rear plug, which looks like a solid copper .223 wad cutter, displays deep penetration. Parts of the front half of the MK318MOD0 round were recovered in the gel but the rear half penetrated through and was lost. The top track is that of the 55 gr XM193, which yawed and then arced downward through the gel. The front half of the round penetrated the gel and I recovered it from the ground below the gel.

The rear section of the MK318MOD0 pictured came from a separate test as I was unable to locate that part of the bullet after it passed through the gel.
Ideas
Possible future tests include:
Military rounds - M193, M855, MK318MOD0
Fragmenting rounds - Hornady TAP, Winchester Silver Tip, Remington Disintegrator
Expanding rounds - Federal Fusion, Barnes TSX
A Frame rounds - Nosler Partition, Winchester PDX1
ComBloc rounds - Tula / Wolf, Brown Bear / Silver Bear
Effects of rounds fired through barriers - I'm particularly interested in seeing the results when fired through soft body armor
Comparisons of various calibers - .223, .308, 9mm, etc.
Check to see if there is a correlation between ordinance gel and Perma-Gel, possibly a conversion formula.
I'd like to make the following improvements:
Construct a support structure to keep the gel from falling over and to catch rounds that escape the gel.
Obtain a chronograph to measure the speed of the bullet just prior to impact with the gel.
Move the camera closer to the gel (obtain measurement of the ideal distance between camera and gel).
Clean the gel. There are fragments of rounds (artifacts from previous tests can be seen in some of the posted pictures) scattered throughout the gel. I've read that the gel can be filtered through nylon.
