Okay, I guess nobody wanted to play...
I tested various loads and bullet configurations on water filled, 1 gallon milk jugs from ~ 8 feet.
Here's what I learned about the hollow point in a CZ:
The un modified Seirra 85 Gr. "sportking", with 13.5 Gr. of H-110, average MV 1548 FPS, penatrated 3 jugs and stopped ~ 6 inches into the dirt backstop. slight mushrooming of the tip.
The modified,hollow pointed, 75 Gr Seirra, with 13.5 Gr. H110, average MV 1550 FPS, exploded in the first jug. full jacket separation and lead fragmentation, pieces of lead and jacket found in 2nd jug. (Absolutely shredded the first jug)
85 Gr Hornady with canalure, 13.5 Gr. AA9, ave. MV 1660 FPS, stopped in 3rd jug, fully mushroomed, almost to the canelure. retained weight 83 Gr. ~.650" diameter. This one hits HARD.
Conclusions:
The unmodified "sportking", @ 1540 FPS, will almost certainly shoot through a human, with enough retained energy to punch threw an interior wall on the far side, or another body. (I want to test this load on a live hog, but I suspect it will go thru and thru, even hitting bone)
The modified "sportking" is very frangible, ALL energy is transferred, with minimal penetration (4-8 inches). Not the load I would use on something I want to eat, lots of tiny splinters of lead and jacket material. A lightly clothed Zombie, hit COM, is certainly DRT. I'll retest this configuration with several layers of heavy cloth in front of the jugs, to simulate heavy jacket or coat. An interesting side note: no difference in 50 yard accuracy was noted, still easily "minuet of pop can" @ 50 Yds. (2 inches)
The 85 gr. Hornady soft point, @1600 FPS, will easily shoot threw a human, but likely create a very large wound channel and, perhaps, not penetrate another human or an interior wall on the far side. (but it's gonna leave a mark.) This would very likely make a good hunting/varmint load, for use under a hundred yards. (yep, with a pistol) I want to test this load on a car body and balistic cloth. Might be very useful for urban/social work.
The next round of tests will be done with the 85 Gr. Hornady, with both deep and shallow hollow point, at several lower muzzle velocities. This bullet seems to have a stronger/ heavier jacket that retains the lead core better than the Sierra, under expansion. A drilled hollowpoint cavity might start the expansion sooner, reducing the penetration, at a lower velocity, without losing the expansion. The goal being, ~10 inches of penatration with double diameter expansion.
I know that water filled jugs arn't going to give "real world" performance data, but I can't afford to play with balistics gel just now. If anybody does have access, I'll gladly provide some test ammo.
Furthur testing will be needed with the PPS-43, 10 inch and 16 inch barrels...Wait for it.

Edit, PS, I opened a spam can of polish millsurp today and pulled a bullet for examination. The jacket is STEEL, heavily brass plated, (.003-.004") the lead is exposed at the base and swedged concave, similar to a HBWC. I would definatly NOT recommend cutting the nose off this stuff and firing it. You have been warned...
