Current Hatsan Sortie Tact Air Carbine?

If I use the correct settings and pellets I have no problem with the magazine jamming or the gun firing in semiauto mode.. If the bolt does not retract completely it will not allow the magazine to rotate but this is not jamming. If I want to test a magazine I load it with pellets and then use a rod of the same diameter as the bolt and manually push the pellet through and see if the magazine rotates when you withdraw the rod. Continue to do this and empty the magazine. If the magazine does not rotate and feed the next pellet when you withdraw the rod completely then something is wrong with the magazine. 

I plan to start selling my collection since I am now 88 years old. I have a walnut stocked Sortie I would sell if you are interested. Please contact me at [email protected]
