My thing with these expansion results is that this is only when shot into water. Which really only shows part of their potential. For example, the first image is a 21gr .217 Javelins slug shot at 960fps shot into an iguana at around 50-60yds. You can tell that the HP definitely did it's job! But it doesn't expand perfect like a pancake.
That massive mushroom pic was a hn hunter extreme. The Hades was the lightweight 25. The 22s did great for me at 850. Maybe the monsters are harder. I don't know. That 10mm expansion was shot into my rendition of Paul Harrell's (praise be upon him) meat target
. I use a leather razor strop a thick layer of tallow either a bone in chicken breast or Cornish game hen, the innards packed with tallow and gizzard or soft butter. Same results from 10% ballistics. 
That's interesting maybe you missed hitting the bone? I know I broke several bones in the iguana, hit the scapula, along with several ribs which explains the deformity.That massive mushroom pic was a hn hunter extreme. The Hades was the lightweight 25.

Off the subject of pellets.. check out what this LDC did to this squirrel. Btw I ported the notos to 4.5 and worked it a bit wider with a burr. I added a little weight to the hammer and I'm shooting the griffins at 840 now @ 2400psi. Full hammer spring. And this is the effect the LDC is having at 88.5y.

While hunting, when shooting projectiles reliant on expansion to give the most humane death.. I shoot for eyes, or dead on between the eyes to burst the skull, or purposely shoot vitals through the meatiest path possible to get that effect. but, headshots that did pass through skull always expand fine. You're hitting shoulder, ribs then vitals flank on. It's gonna happen. Bones become fragments too. Ive never shot a reptile. I just picture a scaly squirrel. Lizard skin is definitely tougher than flesh without the keratinous cover like rodents. Try on quartering away shots to come in just behind the back rip through diaphragm, into heart and lung. Or under neck through the thoracic cavity over the first rib.
Well typically I go for headshot and try to steer clear from vitals as unless I am shooting .30 cal a vital shot wont be good unless I can align it with a spine shot. These guys are very resiliant, but I have seen in more and more posts that the fur on a squirrels skin aids in retaining the slug or hunting pellets, and preventing them from exiting most time.
Iguana bones are more like chicken bones, idk if chickens have harder/stronger bones that your average bird. The ribs are flexible on an iguana though.
I'm bringing some Hades tomorrow morning. If I get a chance I'm gonna take a squirrel for it. I'm pesting at a friend's home, they have a small
I've experienced really good expansion. Squirrels are 5050 on pass throughs.
The birds were thick all morning. I haven't seen a rodent yet. Actually it just started raining. I'm at 43 winged rats since 8am
RMR Bullets are cleaner, cheaper, exactly the same and shoot just as well. I have my Dynamic tuned for these at 900 fps and very happy so far
I've installed the 1:16 slug liner.. hybrids don't like it. I'm doing point of aim point of impact every shot on Zan's and h&n 30gr. I'm sticking with them
have you found the 1:16 shoot those slugs a lot more accurate and consistent than the 1:24 Superior liner? what kind of improvement have you gained? like going from 1.5" at 100 yard down to 0.5"?
Not something i would repeat, these 38gr NSA slugs are going to need at least 750fps for clean kill.
