Hatsan Jet I/II Discussion

[EdinGa]

The .177 barrels are a problem. The pellet lead in mine was ground slightly off center, and extended WAY past the transfer port making the useable length that much shorter. Lastly the star shaped crown was an attempt to choke the barrel, it was way over done and distorts the pellet shape. Hatsan should replace the .177 barrels under warranty if they were a serious company.

Dang I should have asked around about the .177. anyone pulled the barrel on one of these?

I have the barrel off mine right now. There's 2 grub screws holding it. One on each side of the receiver.

Hummm had them out guess I didn't pull hard enough to get it out.

I've read a lot of Jet posts on different forums and the only complaints have been about the .177  not being accurate. Posters seem happy with the .22 and .25

Wait a second, it's been a couple of weeks since I took it off. I think there are 2 screws stacked in each hole.

[EdinGa]

I looked through the parts I took off and if the screws were double stacked, I've lost 2 of them. I don't remember my barrel being difficult to remove though.

[JPSAXNC]

There's only two screws holding the barrel in. Google (Hatsan airguns exploded views), scroll down the list to the Jet.

[miksatx]

Yup 2 for the barrel and 2 along on top of the barrel. So pulled the barrel and pushed a couple pellets through they both hung up on the crown. Recrowned it will see how it does in the morning,

What's the barrel diameter on these?

[miksatx]

What's the barrel diameter on these?

The .177 =12mm.

[EdinGa]

12 mm for the .25 too.

I'm considering buying the jet and was wondering what .25 pellets if any don't play well with the mags?

[EdinGa]

I'm mainly shooting my cast pellets in my .25, but I did try Hades and Crow Magnums and it shot them both well.

are you using your cast in the mag or single load?

I've shot them both ways with no change in accuracy.

Didn't do to much better this morning got the spread to about 3/4" group. Pulled the barrel pushed some pellets through still had a tight spot. so cut off a 1/4" recrowned. Shooting much better with chps that's a plus.

 I was just shooting my Jet 1 in .25 and was getting great accuracy with the Benjamin .25 pellets, I shot 100 or so, then got the bright idea to regulate it up to 3000 psi, well first shot blew out the valve poppet  Stripped it down to the basics will be going inside when I calm down LOL

[JPSAXNC]

James, Did it blow the poppet through the Delrin seat? Did you happen to crony it on that shot?

[aimsmall]

Just bought the jet 1, midways price just seemed to nice to pass up. Grabbed a tin of hatsan pellets as well.
Hope it's a good one out of the box, first hatsan ever...

I more than likely did blow through, I was ailing over the crony, but it did not register and the gun did a total air dump from 3000 psi, well I did shut off the asa valve with enough air to do a couple diagnostic leak test to make sure it was the poppet. Will try and do an autopsy tomorrow.
