Did wak a starling at 20 yards, with a 16g hades would have had an impact speed of 950fps, that was impressive, went down like he been hit with a 17hmr. ]]> Tue, 16 May 2023 08:21:07 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6851#6851 Crossman HPs : kuzzaroad is correct on this one... www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6850#6850 Author: dvlnme

kuzzaroad is correct on this one you need velocity to make a soft lead hollow point bullet or pellet to expand reliably,accurracy is the key wih airguns,its generally accepted by lead bullet shooters using firearms with hard cast bullets or soft lead swaged bullets that it takes close to 1000fps on target to get any lead projectile to expand reliably in flesh,they may doso if they hit bone but not allways,a pcp rifle firing soft lead hollow point bullets at over 1500 fps at the muzzle is a very differnt thing to a pellet gun firing pellets at under 1000fps,and most accurate airguns are under 1000fps,i have been shooting all sorts of lead bullets out of firearms for lot years and done lot hunting using lead bullets in firearms and pcp airguns,and i can pretty much garrentee hollow point pellets except for polymag type pellets never expand in small game at airgun velocitys a domed pellet hitting small game animals at anything over 700fps will do a lot of damage evan in 177 cal with a head shot its instant lights out on rabbits possums etc,having tryed most hollow point pellets in 177/22 cal none ever expanded until they hit the ground behind the target except for polymags at airgun velocitys but surprisingly sometimes hollow point pellets can more accurrate than domed pellets,so you pays your money and takes your choices eh,just find the most accurrate pellets for your guns is allways the best choice for hunting or pest shooting.

From what I've seen and checked on reviews I don't think springers really have the omph to get good expansion.
Your never going to get the expasion of what cartridge rifle will do due to the volicity dropping so quickly.
Accuracy has always been the mantra of air guns for pest control.
Expansion rates in gel arnt that applicable as its not an accurate medium for small game.
However the expansion when hitting steel catch boxes seems to be pancake like in my experiance. ]]> Tue, 16 May 2023 03:38:16 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6846#6846 Crossman HPs : I've not had much luck with... www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6840#6840 Author: jwabfrog

I've not had much luck with hollow point pellets achieving any mushrooming. I shot multiple 22 hades in my Gamo magnum and never found one that had achieved any form of expansion when I dug them out of bunnies. I've found Crosman HP can give good accuracy and I'd buy them for that reason but not because I think they're any better for hunting. ]]> Tue, 16 May 2023 02:40:17 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6840#6840 Crossman HPs : Yep the crossman design with the... www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6817#6817 Author: flock

Yep the crossman design with the right softness of lead would be ultimate, at 6 fbs they is only pushing 420 fps have to re do the experiment with the TX200 at 14 flbs.The thing I saw on U tude was Yanky with a Pcp doing stupid speeds that couldn't possibly be accurate.]]> Mon, 15 May 2023 03:55:22 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6817#6817 Crossman HPs : 👍🏻I’ve often wondered... www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6812#6812 Author: RangerPete

👍🏻
I’ve often wondered about this…
What is required to get a hunting pellet to expand and turn into a “mushroom”???
Obviously this is only relevant to “hunting pellets”, wad cutters for paper target shooting and pellets just for plinking don’t need to dump energy, mushroom and deliver devastating terminal perform, they just need to be accurate and hit what u were aiming at.
I think there are 3 factors that contribute to how easily a pellet will mushroom (ie dump energy and create a bigger wound Chanel):
1- hardness/softness of the lead. - softer lead will deform easier.
2- shape of the pellet. - a hollow point will require less energy to expand then a pointed pellet.
3- velocity/fpe at impact. - the faster it’s going the more energy it will be carrying to help it deform.

I think most hunting pellets are made from lead that is too hard, I.e. they don’t mushroom at practical velocities.
Imagine if pellet manufacturers made specific pellets for different energy guns!
For example a JSB Hades in .177, 8gr that is designed to mushroom and expand to twice its bore diameter, at 10.5fpe.
And another JSB Hades also in .177, 8gr, but made from slightly harder lead designed to expand to twice its bore diameter, but at 20fpe.

I guess that’s how things progressed to slugs… use a softer lead, make a deeper “hollow point” cavity, and push it faster!

Sure would be great if we had pellets that mushroomed at lower velocitys!]]> Sun, 14 May 2023 17:07:23 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6812#6812 Crossman HPs : No standard jsb domed pellets www.kiwiairgunners.co.nz/forum_posts.asp?TID=810&PID=6789#6789 Author: flock

Hi Flock,
Which JSB’s did you test, did they also have a hollow point?

Brain fart those Crossman Hollow points in 177 look the business,
did an expansion test at point blank range into  water, 
  using a 6 ftp HW45 pistol. Here are the are the results.
Pellet grs speed/ power mm Xmm Expansion
Accupel 8 6 ftp 4.5 4.59        0.09
JSB 7.7 6 ftp 4.4 4.57        0.17
JSB 8.5 6 ftp 4.35 4.54        0.19
Crossman HP 7.8 6 ftp 4.49 4.5         0.06
 So the Crossman are too hard, with the JSBs  winning quite considerably
