JSB IS On IT! JSB King Heavy 33.95gr

[Bwalton]

Dear Baxter,

 

Thanks for your e-mail and feedback on our new product. We were already informed by our customers that the pellets are not working correctly in the magazines of some airguns. To tell the truth we didn’t have such a problem in our testing Daystate, Air Arms and Edgun rifles. In spite of that we have already started to work on updated version with smaller skirt diameter. Thanks for your understanding and patience.

 

Best regards,

 

Pavel

Good news.
I have two tins coming soon.
I will test them, too.

[Bwalton]

JSB is keeping me posted should be able to test the NEW! dia skirts much like the JSB Kings soon!

[Nomadic Pirate]

Hope they don't change a thing !!!!..... they shoot perfect and load perfect in my Rainstorm.

[Bwalton]

That's strange, nappy has the RSII in .25 and was not good in the clip, We tested them in a bunch of other rifles also,  Have you pushed a pellet thru your clip? Well JSB has received a overwhelming number of complaints, enough to make a revision.


 Mine will load, but very tight, the groups are not bad, but not what the rifle shoots. Just outside a dime at 50 yards, but I'm more inside a dime. Could tell something was not right.

[Nomadic Pirate]

They load just fine in the mag, just need to push them all the way.

You guys might have gotten a bad tin because others are having exceptional results

[Bwalton]

we have 20 tins......

[tkerrigan]

I've fitted them to Marauder, Kricket Carbine, Hatsan, and Sumatra.  The only tight one was Sumatra, but doesn't appear to scrape anything off the skirt.  I was going to relieve the Sumatra mags a little, but will wait if the skirts may be made smaller.  Regards, Tom

Hatsan for a fact is a no go, Thy were tried in Daystate, Evanix and there is a video of the Cricket being to tight, just because they work, and like I have said and is on my video outside a dime @ 50yards does not mean that they are the right size here are the two videos to refresh the memory. Just to add while these groups may seem great for some they are not my ideal group or the size that comes from my rifle.

I have an FX Royale .25 cal.  The new .34 gr JSB will not function in my magazine.  As mentioned the skirt is a little wider, getting past that, it's to long for the magazine.  In my magazine, it is just long enought that I cannot advance to the next slot to load another round.  My single shot tray was also a little small for the larger skirt.  I modified the tray and now it loads without issue.  As the bolt is chambering the larger round, I can feet the difference when it inserts in the chamber. It shoots and holds good groups, but I think I'll stay with the .25 gr pellets.  No issues in the magazine or feeding, also better groups at the same distance.  This is after a full tin of practice with the .34 gr JSB.

There's one guy that they worked great for, he single load them so that maybe why they're working for him.  As accommodating as a Sumatra magazine is, these pellets are way too tight,  I have to force them down with a 5mm allen key.

tell Nappy to PM me, those pellets load just fine he must have not pushed them enough.

ho yeah, I buy 10 tins from you guys since you don't like them

[Bwalton]

PM Drig I left hem all with him. I think he likes them but he might sell a few, I had him resize a tin for me the same size as the Kings going to use the re sized ones this week on a hunt. So yeah PM Drig.

[Nomadic Pirate]

So Nappy just told me they fit in his mag, no room to spare but they cycle, just like I show in my pictures

[Bwalton]

Yes they fit, they fit in mine too after the skirt is scraped up, did you push one thru your clip and look at the skirt to see if it comes out just like it went in?  is what I am saying, too tight and it deforms the skirt. If they work for you thats great to hear! I shoot nothing but JSB...I still get a Penney size group with the King Heavy also, but my gun shoots better then that and the deforming of the skirts causes long range problems. JSB I'm sure their intentions were for the pellets to fit accurately in all guns, like all of their pellets do. If it was not a concern I do not see JSB addressing the problem for one or two rifles.

This is how it looked only being pushed thru the clip

[Nomadic Pirate]

Nope, the pellets when pushed into and than out the mags still look great.

Thats great! You have got a winner! Now what to wonder......what batch is that from? Oh Manny could you tell me the skirt size please wondering if you have the same size skirts as myself and others, .260 or 6.60mm

[Nomadic Pirate]

I guy from Kalamazoo sent me a tin, I have no tools to do measurements

[Bwalton]

ouch! Thanks....now its killing me to know that skirt size, oh well.... I will be out this week with some re-sized heavies. They are a great pellet don't get me wrong I have a whole lot in store for these pellets

[Thumper5102]

BWalton,

I hope they come out with the new batches soon, I like the weight of these pellets. I also hope I can tell the difference between an old batch and a new one. Also, yes, they fit pretty tight in my Cricket's 5 magazines. They also feed rough from the magazine. If the skirt was .255.... It would be so much better than .26, which is what I measured my batch at.

[Yarp]

Lot 546398-150 : big ones
The skirts have a diameter of .261.
I forced five through a Hatsan magazine, and they all ended up with even symmetrical compression to a diameter of .256

I think if I recall they said that they will be the same dia as the Kings!
