JSB UltraShock .22cal
●Max. Velocity?
●HP Expansion?
●BC?

Yupp, that's what I'm interested in.

(1) What is the max. velocity where you still got acceptable precision/accuracy?
(Specs: ▪What range | ▪velocity | ▪group size | ▪shots per group?)



(2) What kind of expansion did you get of the hollow point?
(Specs: ▪Impact velocity [or muzzle velocity and range] | ▪ballistic material [what kind of ballistic gel, or what animal] | ▪how much did it expand [photo?])

● Did you do anything to increase expansion, like widening the HP cup, making cuts into the head...?



(3) Did you do any BC measurements?
(Specs: ▪What range | ▪What BC calculator did you use | ▪Did you enter atmospheric data?)


Thanks a lot for any light you can shed on this pellet that seems to live in the shadow of the JSB Monster Redesigned!

Well, anybody got any opinions or data on the JSB Ultra Shock?
Thanks.

I have not tried them. I was going to order a tin, but research said they only shoot well in a few rifles. I'm guessing they like low-speed similar wadcutters. With the proper setup, they are said to be devastating.
I passed on the buy because with polymags; I have the same thing but with a bc advantage.

Jon,

thanks for your input!

Are you saying the Polymags have a higher BC than the UltraShocks? Would you know from where you have those BC numbers?

Ballistic numbers can be found on Hard Air Magazine .0013 higher than poly-mag .0012. (oddly poly-mag allows shoot higher than their bc number)
When I looked at them it was in .177. Tracing my steps GTA has several threads in .22 with happy shooters and kill pictures; .177 not so much.

Jon,

my AG mind has a single track. And that track is 0.22" wide....

I should have thought of other calibers that these pellets come in....

In .177 the difference in weight between Polymag and UltraShock is small:
8gr vs. 10gr.
And the UltraShock is a medium heavy pellet for the caliber.

In .22 the difference in weight is huge:
16gr Poly vs. 25gr UltraShock.
The UltraShock is super heavy for the caliber.

Because of the weight difference in .22 there should be a fairly large difference in BC. Not so much for .177....




➔ Still looking for some .22cal info on
▪ max. velocity where you still get good precision @50y
▪ how much hollow point expansion did you get in game or ballistic gel
▪ your own BC measurements


Thanks!

Never used them but sterlock has them at a BC of .023 for the 25.4. Hope it helps.
