JSB Heavy Ultra Shock .22

[Habanero69er]

Ivan, you're right. No where near .047. Not sure where he got that number. I should have checked that myself before posting the link.
My apologizes.   

[Air Rifle Activities]

No, Dave, you don't have to apologize, there's nothing to apologize for! You've been very helpful, I learned from your posts plus I'm grateful that you replied at all. Certainly, anyone would assume that if someone is proficient enough to start writing a review and measure pellet velocities at different distances, that someone would have the common sense to use a verified ballistic calculator
Maybe there was something wrong with the Hawke Chairgun app he was using or the data input was incorrect... Btw, in my opinion the case is the same with the BC of the JSB Beasts .22... The number he indicated is getting too close to the ones of firearms projectiles.

[Habanero69er]

I reran the Beast BC & with the velocities he supplied, the BC is .052-.055, which still isn't too bad for a pellet but no where near what we thought it was. 

[Air Rifle Activities]

Yes, Dave, .052-.055 must be correct. 0.050-0.055 is the BC of the JSB Exact King Heavy .25, which, I'm sure you are aware, is technically the same pellet design and the same weight as the Jumbo Beast, only larger caliber.

Beasts are in and Habanero will be the first to get his.

Joe, what are the head, waist and skirt diameters on this beast of a pellet?  Also, overall length?

People talk about skirt depth.  What about the skirt thickness about 1 mm from the back?

Pics of the nose and tail would be appreciated.

Are dings in the skirt, like the one in the picture typical?

[Habanero69er]

You're still on the fence about these? You can compare the Ultra Shock to the other pellets in the picture if you're worried about length.

L to R: 18g JSB, Ultra Shock, 32g Eun Jin, 34g Beast, .25 JSB King Heavy

OK.  How long are the other pellets?

[Air Rifle Activities]

I'm in a different time zone but later today I could give you the details. I just need to get home after work. Btw, if it is the size of your mag that bothers you, I have a AGT Vulcan and they fit the mag with no problem at all. Kalibrgun Crickets too.

[Habanero69er]

Dimensions of Beast: 10.69mm (0.4205") total length, 1.32mm inside skirt.

Thanks, Dave.

BC for the JSB Ultra Shock Heavy in .22


There isn’t much info out there. I found a couple of tests done by Airgun Shooting And Related Activities.


2017:  32FPE gun.  Distance 31y
BC = 0.022BC (GA)

2017:  35FPE gun.  Distance 50y (numbers converted from metric to imperial)
BC = 0.022 (GA)

There is a widget for calculating B.C. from point of impact under toolbox in Chairgun...

Here's a couple of pics (thanks to ASRA's video).
