Just got a batch of the new JSB Beast pellets

[rsterne]

To get the 34 gr. weight, I would think the skirt is not all that deep, but it is something to check.... I just measured a PRod magazine, and it looks like these are about 0.020" too long to fit without modding the mag....

I tried them at full power at 30 yards, about 940 fps and they didn't do well at all.  I'm going to take the time and lower the speed to see if they shoot better.  I tried them in my older Sumatra and I think the barrels are larger on them.  So need to also try them on the newer model too before I make a judgement. 

[plinker81366]

was the barrel bore cleaned and reseasoned?

Sumatras don't need much maintenance, if a pellet shoots well it will shoot.

[blackdiesel]

They shoot like poo in both my Sumatras on high power.  I'm still going to test them at different speeds, so maybe all is not lost.   

[Nomadic Pirate]

That doesn't sound promising at all,....pity.

[Habanero69er]

I'm hoping they'll work well in my Rainstorm. Pretty much everything does.

[PakProtector]

I think I will have to get at least one tin to try. I know my Marauder can deliver the goods, and the 23" LW should do it if any will. IF not, I can try the BSA tube and see if they like it any better...

Also, I am pretty certain they shoot well in *SOMETHING*...call JSB and ask what they tested in?
cheers,

I still find it odd that they (JSB), don't even mention or list them on their website.

[Mod90]

not really that odd Dave. maybe they just didnt update the site yet, or possibly since its a new concept they're waiting on feedback from the air gun communities to decide whether or not to push this particular item or scrap it outright.

Just some video info of the beast...

Got my order of .22 Beasts & Ultra Shocks. A little photo comparison:

L to R: 18.1 JSB, Ultra Shock, 32gr Eun Jin, Beast, .25 JSB Heavy




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

I'm going to try them out in my Rainstorm & even in one of my 342s just for $h!t$ & giggles. Kinda breezy today, but it's coming directly out of the north, so I'll be shooting directly into the wind. Shouldn't be that big of a deal with such a heavy pellet. I'll report back on what I got.

Nice of you to show the skirt depth difference, good luck with the testing...

Bob was correct in the skirt being shallow due to being able to get the heavy weight on the beasts...

They're looking more like bullets. It'll be interesting to see how twisty rates play with them.

I knew that was one of the questions that needed to be answered for anyone interested in trying them out.

Indeed Bob was correct in his assumption. Made good sense, as usual.

[Habanero69er]

After shooting a magazine of each:

.22 Beasts, 10 shots @ 25yds, RS-1, measured 12.25mm


Expansion comparison of the 25gr JSB Ultra Shocks compared to 19.09gr H&N Hunter Extremes & 28gr Eun Jin domes.
I couldn't retrieve any of the Beasts because they really penetrated the 7/8" corded hard rubber backing I use to quiet my Champion bullet trap. I'm impressed with both the Beasts & Ultra Shocks. 


I plan to chrony the Beasts & Ultra Shocks tomorrow.

[Dairyboy]

Looks like the shoot pretty darn good out of your gun

[Nomadic Pirate]

Good showing in the Storm
I knew the Ultra Shocks would be good , my old Storm loved them.

[Habanero69er]

That rifle shoots most everything well. It would have done better if I had a steadier shooting platform. My table isn't the steadiest thing in the world & my 4yr old granddaughter was playing spotter for me, but kept bumping the table. There I go, blaming it on the table & a little kid!   

The expansion of the Ultra Shocks is pretty darned good. Penetration of the Beasts was also very good. Both pellets I'm guessing are probably shooting in the 45-50fpe range. I'll know better tomorrow.

Do the Beasts fit the Rainstorm mags?
