Hatsan Bullboss .22

Is it stock? No reg? Have you adjusted the hammerspring?

What Kind of Power do you have?

Chrony numbers?

Does it sound different now then it did when you got 40 shots? I had this same issue with my bullboss .22. It was the anti bounce mechanism. It had a bent pin. This may be your problem as Well. Email Hatsan there service department is b.s. but they will eventually get back to you

Often the new guns have oil in them from the manufacturing process. This could cause a lot of dieseling and throw shot curves and shot strings out of whack. I don't think that it is that although. I had have a 22. Gladius, on max power with the hammer set to max and when it is unregulated, I did get many more shots than you did, maybe the minimum was 28-30. If you put a de-pinger in the reservoir, a piece of it could have came off and got stuck in the valve door and stops it from shutting quickly, therefore waste some air. That has happened to me before with a different gun. But I don't know what the problem is for you. It's a mystery.

"npetro"Yea sounds louder!
is it a pain in ass to install?

If you are referring to the anti bounce mechanism i do not know. I had to send it to Hatsan for repair. It does get louder when the hammer is bouncing on the valve. It may also sound baffled like a loud quick fart instead of a solid release of air when fired. Your fps my not be affected but your shot count sure will.

And your old numbers were?

You are shooting very light pellets. I understand you think you were getting more shots but simply using a heavier pellets will increase your shot count in this case.
So let's have those before numbers.
