Tuning Hatsan Magazine BullBoss Problems

[Chopper61]

So some pellets are getting jammed and very hard to load, seems like or they are getting hung up on the prong? Freaking Another Chinese made issue! Any feedback from my fellow gunners would be appreciated. I’ve tried stretching them and others prongs someone must have a remedy?

Hatsan are not Chinese made they are Turkish made with extremely poor terrible machining even worse than China.

Try a different magazine and seat the pellets good or try shorter lighter pellets.

Yes thanks I have a total of 14 magazines, 6 work properly. To answer your question I like shooting the H and N 31 grain pellets not sure yet on the different type of slugs, they will take Grizzly’s tho but not consistent accurate I like hitting with authority and dead on accurate which this gun does. The problem lies with certain o-rings they install. The head grabs the second o-ring which keeps it from sliding in! Maybe if I soak them in Ed-40 or I wonder if 1 bigger o-ring will work? Idk

Alphabet org Auto trans stop leak quick fix the all purpose one that you can add to both engine oil and transmission fluid.

Oops that may not work that's used to swell up fatten the o-rings.

Address your bad magazine issue with HatsanUSA maybe hopefully they can swap you for good ones maybe the grooves are simply poorly machined cut too deep if larger o-rings doesn't fix the problem.

You can try stretching them then taping the o-rings to a funnel to stretch them if you don't wanna buy new o-rings if you don't own the expensive conical measuring tool.

Use tape as a stop point larger than the size you want because it will shrink smaller. Lube with Alphabet org before sliding over the funnel. Let sit for at least a day or 2.

I have found that in order for them to function smooth one needs to lube the o-rings with silicone grease . That's what I use on my 25 cal. or they are hard to load in the chamber. Do you seat the pellets (tap the mag on something flat and solid ) ? That helps .

Use a dremel to smooth the rough edges of the magazine. You will have to go through all 9 slots on all your magazines that are troublesome.

I had the same experience with one of my .25 hatsans. It wasn't the oring.

Well I have found the problem lies with the second o-ring that’s facing towards the muzzle of the barrel. The head of the pellet is hard to get past that second o-ring. I like to shoot domed pellets. Greasing the mag with silicone, not sure if that puts any extra residue in my gun? Anyone know if these o-rings serve a purpose in the sealing of pressure at the receiver, or are they just there to keep the pellets in place? What about just 1 o-ring to use? To keep them in place.

All my magazines were purchased through Pyramid Air, they replaced them immediately which is good customer service. I don’t understand however how you can have a good one out of every 6 bad ones. They must be doing slave labor were they are dealing with thousands of different o-rings and putting the wrong ones in at times. Obviously you can tell it’s frustrating to me. I know I’m not alone either. These magazines aren’t free

 

[Seth0764]

There should only be 1 oring on the magazine and it holds the pellets in place. The next oring is the breech seal necessary for sealing pressure in the barrel. 



You probably have rough spots or burrs in the magazines 

 

[Chopper61]

Ok thanks but confused. There r 2 o-rings in the middle of each magazine

 

[Seth0764]

I checked the diagram and the .25 does have 2 orings on the magazine. Sorry to confuse you. Nevertheless i would clean up the sharp edges and deburr the insides of the magazines its common hatsan issue
