Hatsan Factory Problems with the Warranty

[Geoff]

When you pair these together in a super magnum the air blow by around the pellet through the rifleing does not allow the piston to decelerate thus slamming into the end of the compression tube.

Hatsanman13 was just in chat tonight relaying what Hatsan has told him about his gun and that was what they said.  They said Crosman pellets were inconsistent in size and that blowby will cause damage due to low or not enough backpressure.

its also been said in most of his posts that people have commented on that its the corsman pellets.... so I'm really not surprised that Hatsan agrees.

I have owned a Hatsan 135 for several years now and have shot all kinds of pellets through it. For hunting inside 20 yards I have used Crosman Destroyers exclusively. For target shooting I used mostly JSB's but have shot a lot of Crosman HP's and other pellets through it. Some of you may remember that I had a lot of issues and sent three guns back to Pyramyd Air before I got a good one. That being said I'm really happy with the rifle I have. The bore of my gun is small and even Daisy HP's fit tightly. Hatsan blaming Crosman pellets for their quality control problems sounds like bull scat to me. If blowby is a problem it's likely because they had a run of oversized barrel bores. The best thing the OP can do is like others have said contact Rick Eustler.

This is a very interesting thread!  I guess I got a relatively good 135.  When I got my Hatsan 135 last year I did a fair amount of chrony testing (please keep in mind that these results are from a period of time when the rifle was brand new and was still smoking quite a bit).  Bottom line is that I would not rule out shooting .22 CPHP from a tin. 

They may be inconsistent in head size (yes, some fit loose while others are tight) but at least in my case the velocities are pretty consistent.  To me this would indicate that even though the pellet material is pretty hard, the skirts probably DO flare while going down the pipe.  Again, your results may vary...

Oh, by the way a couple of these strings are 20-shot strings while the balance are 10-shot strings.

But for accuracy it is hard to beat JSB 15.89 or 18 grain pellets
