FPE needed to deform a pellet???

That is very interesting. Do you have any pictures of these pellets, maybe before and after and the stats on weight, fps and fpe?

I'm not really into stats like that. I'm a hunter and plinker mostly. Several of us over on GTA did do some testing with them a couple of years ago though. I don't know about posting a link here but it should be easy to find there with a quick search.

Here you go.
They Daisy HP expanded even at a very low impact velocity far below 700fps!
With 100fps more it would probably experience a huge expansion, resulting in a huge-for-caliber wound canal.
➠ Good killin'.

Thanks Matthias! I finally found a picture of a Daisy HP that I recovered from a chipmunk at 23 yards. Muzzle velocity was around 630 fps.

The .22cal Daisy hollow points really turned out to be a pleasant surprise. All my earlier experiences with Daisy pellets occupied the spectrum of bad to atrocious, so at first I was hesitant to even try them. But if I remember correctly, it was in large part due to Ed's report that I decided to order some. They quickly proved to be an excellent pest control pellet, being both accurate in multiple rifles (~1/2in at 30 yards) and delivering expansion on actual game, not just in synthetic tests.
The example documented by Matthias above was an early one I retrieved from a gray squirrel. Here's another example I captured later showing the shot placement:

Quick summary
- 26.5fpe muzzle energy (883fps)
- 16.8fpe on impact at 30yds (704fps)
- Vitals shot. Soft tissue only. No bone.
- Pellet came to rest just under the hide on the opposite side.
- Expanded to a frontal area 47% larger than an unfired pellet (0.263" vs 0.217")

Thanks Mattihas and nervoustrig.
That really is some impressive expansion.
I have used the hades quite a lot and I have never been impressed with their “expansion” if you could call it that.
I wonder if I can find some of these Daisy hollow points here in New Zealand
What does the box/tin look like?
Thanks,
Pete.

Looks like you can get the Gamo version. All of these are made in Spain by Gamo. From what I can tell, they are all exactly the same.Thanks Mattihas and nervoustrig.

Eddie,
that is an excellent insight you offer —
the rebranding of Gamo Swarm 10X pellets to
• Winchester HP and
• Daisy HP.
Thanks for that.

Thanks again, Matthias! I remember stumbling across the Daisys on Amazon when they were less than $5.00 a tin. After finding out how well they shot and expanded, I listed them in the bargain gate in GTA if I'm not mistaken. I know I posted about them there and several of us bought all of them we could get our hands on. I think I ended up with 10,000 plus in .177 and 22. They are still my favorite pesting pellets too.Eddie,

Thanks EdinGa,
I don’t see any weights on the tins for the Winchester and daisy pellets, only the Gamos, but I’ll take your word for it and will try get some from guncity. Will try pop in there tomorrow and do some grouping tests asap…

I didn't list the weights but I did weigh them on my powder scale and they are all the same.Thanks EdinGa,

I love how we discuss our air rifle performance like mini high power rifles, but I see the term (hydrostatic shock) used a lot in here and in some videos made by prominate writers. The fact of the matter is hydrostatic shock doesn't occur until velocities reach 2,600 fps. Love the topic and feedback regardless

Hi Buddy,
I have dissected many rabbits and possums that I’ve shot with air rifles in .22 and .177, usually when trying to recover pellets or slugs to see what their terminal performance was, and there is no doubt that there is damage, bruising and blooding caused by the pellet as it travels through tissue.
It’s usually the easiest way to find the pellet, just follow the bruised and bloodied wound channel.
I don’t know if it is technically “hydrostatic shock”, but as anyone who knows anything about hydrolics will tell you, you can’t compress a fluid. So there must be some sort of “shock wave” of compression through the tissue cells as the pellet displaces tissue and forces its way through the tissue, leaving a path of bruising/bloodied meat in its wake.
I dont know if a .177 pellet doing 750fps tearing through tissue produces a big enough shock wave to “rupture cell walls” and turn meat into jelly like a high velocity centerfire projectile will do, but it is definatly doing something…???
Pellet terminal performance and would channels are so interesting to me.
Pete.

They are to me, too, Pete!
Can you share any observations you have made comparing .22 vs. .177 — or comparing different impact velocities?
Or (especially interesting to me), hollow point performance?
Thanks!

The best hollow point performance I have found comes from slugs around the 30fpe mark.They are to me, too, Pete!

That is probably because they are pushed faster than pellets and some have very deep hollow points.
In my experiance most pellets don’t mushroom, even the hollow point pellets.
They might flatten slightly or deform a little, but I’ve never found a hollow point pellet that performed how I would like a hollow point to mushroom.
I shot many tins of JSB hades in .22 at around 25FPE, and even they don’t mushroom.
So I’ve just come to accept that most pellets are not going to mushroom and dump energy into the target, they are more than likely going to over penetrate and exit, regardless of caliber or fpe. So these days when I chuoose a pellet for hunting, I don’t even look at “hollow point” or any other type of fancy design they might have, because none of them are going to mushroom, and they are all going to probably exit, so I choose my pellets according to which is the most accurate (tightest groups) from my rifle, and so far I’ve found nothing that can beat the JSB 8.44gr Exact, so that’s what I use for my rabbit culling and I just accept that all head shots are going to exit, even from my 12fpe .177, and even at 50 or 60 yards. If I’m worried about a richochet and I don’t want the pellet to exit I will choose a neck/chest body shot.

The pellet on the right is a .22 Daisy hollow point that was recovered from a chipmunk shot at 23 yards. It left the muzzle of my Prod around 630 fps or 13 fpe, but still had enough energy to start expanding. The pellet on the left is an unfired .22 Daisy hollow point for reference.

Hi EdinGa,
I did manage to get hold of some of those Gamo 10X hollow point pellets.
I’m still not convinced they are the same as the Winchester hollow point, but anyway.
I tested them on a rabbit carcas and they performed pretty well. They did show some slight expanding, although I definatly wouldn’t say they mushroomed.
They are certainly good value for money, being almost half of what a tin of JSB exacts cost.
The only problem was when I tested them for grouping at 20m they were not too good
. Most of my rabbit culling I do with a 12fpe .177 at distances from 6yards out to 79yards, and for that I need the most accurate pellet I can find.However, I also have a “low power” 4.5fpe setting on the same .177 rifle, which I use for pigeons and ratting out to 22yards, and these gamo 10x hollow points are perfect for that

I'll try to remember to test the hardness on the Gamo 10x pellets I have. They look identical, but the alloy could be different. I'm planning to try and take a squirrel with them sometime soon too. I'll test the .177 in my 13 fpe Stormrider and my 20 fpe bullshark as well. I have a 6 fpe Diana Chaser that I might try to take a chipmunk with at some point too.Hi EdinGa,
