Of all the bullets I've tested in wetpack media, one penetrated through both attempts at stopping it. It is the 450 GS Custom 458 FP Solid. Impact velocity of load out of the 450 Watts was approx 2150 fps to simulate a 50 yd impact. 1st attempt was with normal media of 100% water saturated phone book bundles with a 2" hard wood bone simulation placed between bundle 1&2. Complete pass through of 36" media length. I re-built the trough and lengthened it to handle 48" of saturated, bundled phone books. 2nd attempt with same wetpack/ wood bone media set up and same load was complete pass through. Both tracks were perfectly straight with the bullets exiting point forward.
I give! :) I believe it's safe to say, in that velocity range, that bullet has adequate penetration for any hunting situation I will ever need. Plus, getting enough phone books of the right size is not easy as the phone books in the test are a one-time-use.
Here's the bullet.
