Hollow point devastation?

I used a Beeman Crow Magnum 18.21grns in a .22 M-Rod on a rat, about 15yrds. Not sure about the fps, but it tore the top of the rats head clean off (that was all I could see). Like I could see down into the cavity like I was in anatomy class it was that clean. No brain matter remained at all. 
Not sure about the devastation, but the H&N Baracuda Hunter Extreme Pellets, 19.09 Grains group pretty good in my rifle.

Wow! Those crow mags did a great job on that rat. That's the type of devastation I'm looking for.
 
Predator Polymags top my list in .25, .22 and .177. They are also the most accurate expander in all my rifles beyond 20 yards out to whatever range. 
Myna as it fell (always on their backs)
.25 Predator Polymag:


50 yards 5 shot groups Predator Polymags comparison to the top shooting JSB Kings. And this holds you to at least 70 yards:


.22 Predator Polymag damage:
The breast of this Mynah has been carefully lifted forward to show the damage done by a super expanding Predator .22 at around 820 fps at impact. Mynahs/ Mynas/ Indian Mynahs are one of , if not the most damaging invasive pest species to indigenous birds around the world.


Well you asked for it! :-( ... Harry.

 
I feel I may have put folks off with those graphics. The thread seems dead, OP and all.
If so then please accept my deep apology.
To make some amends -
History: The Predator pellets were invented by Tom May, retired US paratrooper, in a shed in Colorado some 15 years or so ago.
He first had them unsuccessfully produced in China; then went to JSB in CZ who continue to make the lead part. He had them then shipped to Hungary where his very expensive machine is used to precisely install the polymer tips. They are then shipped back to JSB for distribution to USA.
Tom passed the business on to Richard Dixon in USA who distributes them.
So, if you wonder why they cost what they do, then you can factor in the journey they take before your USA costs are then added.
Companies have stolen Tom's design (eg., Gamo) but can't duplicate the precision of any JSB made pellet, let alone the Predators.
So if you buy, I suggest you buy the USA innovation and support Dick's Predator International (and I don't even live in USA).
Again, my apologies if that last response was more than what was being asked for. ... Best regards, Harry.
 
For hollowpoints, I prefer the semi-pointed varieties (Predator, Crosman Destroyer, ect). So far, the best results I have had have been with Beeman Terminators in .22. I wanted to fall in love with Predator Polymags, but all my rifles hate them like poison. 20 yard groupings look like shotgun blasts, so I'm hesitant to even try them for hunting. Terminators aren't the most accurate I've come across (3/4" at 20 yards), so that limits me somewhat to larger pests (coons, groundhogs, feral cats) and body shots. Gamo's Polymag clones (Red Fire/ Blue Flame) are a bad joke; most of the pellets come without the polymer tips, having fallen out during shipping. I want to try the Predator Metalmags though; maybe when the Terminators are all gone I'll give them a whirl.
And Yrrah- Nice Pictures! We can all debate groupings, velocity, and ballistic gelatin expansion tests until we are blue in the face, but nothing illustrates performance like some good wet work! I only wish the pellet that did the damage could have been recovered to examine the expansion, but that looks like a clean through-and-thrugh. Metaphorically speaking, of course. Interesting history on Polymags as well!
