JSB Jumbo Beast .22cal @ 33.956gr!

As it stands now the Beast come out of my Condor SS with a PW setting of 7 at ~885fps. If I had a heavier hammer I'm sure the speed would be more. If I put on my 24" barrel my speed would probably be much higher.

They shoot out of my gun very quietly and although I did not test for accuracy they seem to fly very well with no spiraling as they are going down range.

These pellets are designed to be used in a Huben K1 semi automatic airgun in caliber .22. These hubens are fully externally adjustable and are capable of delivering +80 fpe in .22. These hubens hit the Dutch market a couple of months ago and as far as I know every new shipment is still sold before it arrives. They've gained a lot of popularity up here, at least for the semi-automatic part, accuracy wise I don't know. There are some mixed stories about the accuracy...
 
I have a couple tins. Yes, they are heavy. Purchased along with the .22 25 grain JSB's for my Marauder. I have it tuned to throw the 25 grain Monsters at about 830 fps. When I switch to the 34 grain Beasts, speed drops to around 650 fps.

To shoot them effectively I'll need to tune the gun to shoot like it's .25 caliber brother. Easily done, I just haven't had time to do it.

I think our friend in South Africa, Mr. Dubber had something to do with the design, or at least asking for them. Laws down there are based on caliber, not on FPE, so he prefers to stick with a .22 air rifle, and if it throws some serious lead, that's all the better.
