Huben Huben K I 22 caliber Jamed

[airgunmike56]

I am a pellet shooter through and through but I have a few tins of the Huben peanut 33 gr slugs, I new better, I new better , As I put the slugs in my 2024 KI they fit loose , Yep big time jam, With the help of youtube , I took the gun apart and fixed the jam slug,, What a pain in the as-s to fix a jam in a PCP,,, I could not have done the repair with out youtube helping me along ,, Two hours of working on Huben just for a little jam,, OK I admit I am slow and very careful.
I will go back to pellets 25 gr exact JSB pellets and seating each one at one at a time with a pen,,
Mike
I sure the hell hope the new semi auto guns coming out can fit the pellet to the magazine,
Huben KI and GKI dam sure cant do it...

my 2022 K1 .22 loves the peanuts, your mag must be different than mine. i had a .25 K1 that was a PITA, but its gone now.

Really sorry to hear your fantastic Huben had this happen. Anytime you have to do a tear down like that you just hope you can get it back to perfect like it was before. Was the rifling okay? My Huben barrel was really sensitive to any minor inperfection over time. Krazcool had to repair it once for me in fact over a very minor knick which cause groups to all of a sudden open up like a shotgun. Of course Kelly fixed it right the first time.

I agree that it is a shame that more slugs don't fit in the magazine - I think the mag is likely more a limit than the barrel (especially true if one has multiple barrels, as the mags cost as much or more than the barrels and don't offer much known dimensional change).

The one good thing you have going for you is that you have now taken it down once, and any future take downs will go much faster. I currently run a Huma regulator in mine as it is more stable at lower set points than the Huben regulator (my gun shoots great even down at 95 bar), but when I want to test stuff I swap in the Huben regulator. This is because with the Huma regulator the gun has to be fully vented to take the gun down enough to free the mag, but with the Huben we only need to vent the plenum with is much faster and simpler.

With the factory regulator in place, and my familiarity with the system now, I can take the gun down to the mag for removal and reassemble it and be shooting in about 10 minutes - without even adding more air back to the gun (assuming it had enough air in the reservoir to start with). But it probalby took me about as long as it did for you the first time. Thus if I wanted to do so, I could pull the mag and directly test slugs in it for fit without risking jams when shooting. I will likely be doing such testing soon as I have ordered a Troy Hammer 3-grooove barrel to test out in my Huben - it should be a great pellet shooter, but I doubt I'll find slugs that will work in both the magazine and barrel as those barrels like smaller diameter slugs (but I shoot pellets almost exclusively anyways).

Anyways, the point is your recent experience with it translates into a lot more speed and flexibility on working with it going forward. I think it is an amazing gun, but it is probably less amazing for folks that aren't able or willing to learn how to work on it themselves.

That 3 grove barrel sounds interesting , Keep us posted on the aftermarket barrel for the Huben,,,,

Curious . I thought for pellet or slug jam, just degas, and push a nonmarring rod through the barrel and push the projectile back into the chamber, and you are done. Not so?

Sometimes the rod can work, sometimes not - it depends if the mag partially advances or not. When it partially advances the pellet gets squished in a way that prevents the mag from rotating back to square. I suppose one could "work it" back to position, but then there would likely be a bit of a brocken pellet floating around in there, ready to cause another jam.

The other factor is that, unless the jam was caused by a single undersized slug, the best course of action is to get the mag out to empty all of it in the easiest way possible. The, with the mag also out the gun, it is easy to test lots of other ammo to see if the ammo should even be tried again or not.

Interesting. Thanks. Have not had a jam in the V2 yet, so did not know this is the case. I thought once a pellet is pushed back into the chamber, it is good. Did not hear about the pellet breaking off. But even then, it seems like the pieces would just fall out. Apparently not?

Regarding testing ammo fit, one can just remove the two loading gate, insert the projectile test the fit - and then use a toothpick or something to push the pellet back out. At least this is my procedure.

Yes when you have a pellet that just drops in , Not a snug fit,,, You might have a jam.

I don't know if any small broken pellet bits would simply fall out or not, but there clearly are spaces in the mechanism for them to jam up so I'd rather just get them out. And I'm not saying jams are always that bad, but it has occurred on mine. You have to remember that the jam is almost always going to occur not on the initial shot, where the mag slot is lined up with the barrel and a projectile is in the slot, but on a subsequent shot where the mag tries to rotate into position but a projectile that was too small has protruded forward preventing the magazine from fully indexing. If one catches the condition at this point, it can be easy to fix - but it can be hard to notice. If it is not noticed, and the trigger is pulled with the mag misaligned, then that pellet will have a serious jam.

As for testing for fit to the mag, yes we can do like you suggest and carefully test them in the mag slot and then back them out after if they don't fit. Unfortunately not all mag slots are the same (nor are the pellets or the slugs) so there is that factor too. With the mag out the gun, it is easy to load all the slots quickly, and then pick up and tap the mag on a hard flat surface to see if any tips protrude from any of the slots - if so, I don't use that ammo in the gun. And since it is so easy to do, we can run the test a few times and quickly assess how good 100 or more projectiles work in the mag with great confidence.

I'm not saying I do this often, but I did it back when I decided to try out shooting several different slugs in my gun. Also, this generally is not an issue for most quality pellets - pellets tend to have skirts that are far fatter than any slug and thus will be retained in the mag slots with no issue. When the gun is working properly, I've never had any jam with normal pellets like JSB 18.1s or Monsters (my gun is a .22). I put that "working properly" qualifier on there because there is another thing that can cause jams as the shot count goes way up (like well over 10,000 rounds) - there is a small spring in the magazine indexing mechanism (part #43) that eventually looses its ability to reset the indexer reliably, and then jams can occur randomly (and often). So if your Huben has a lot of shots on it and pellets start jamming up when they never did before, this is the likely cause. Obviously, mine has been replaced, and I keep a spare on hand.

Good luck with yours!

Sorry, I misread your post. I have a 2022 Huben and the peanut works fine in mine. Tight fit.

Ah...makes perfect sence. Learned something. Thank you.
