Thanks for posting this Andrew. You have done a lot of great work with these gelatin tests. Always interesting and appreciated.
This is why I prefer an XTP or, especially, a WFNGC profile rather than a TC profile for the wilderness. The TC profile seems like it would not take a reliably straight path.
It would be cool if Underwood loaded a WFNGC hardcast like the Beartooth. That might be a better bullet. Granted it won't feed in tight chambers, but DT sells a lot of them at watered down velocities. That profile goes pretty straight through water, so I wonder if it would do better with gelatin than the 220 grainer. Plus that big ol' flat nose and square shoulder profile is nasty on target.
One of these days when I collect a bunch of gallon jugs, I'll try testing again. I tried it before and it blasted through 7 jugs and is just now exiting the Kuiper Belt. On another occasion it cleared five(that's all I had) after going through a leather work glove, a 2X4, and 4 layers of denim. That is a handloaded 200 grainer @ 1205 fps charged with A9. I would love to see gel results for that one.
