FN marked Browning trombone issues :(!!!!!!

[simko]

Got a trombone pump .22 from a member here , took her out for the first time today and having some issues.

When i load her up,. 80%+ of the bullets dont fire, im thinking light primer strikes, tried different brands and loads and still getting the same result: im spending more time with the gun pointed downrange waiting incase i get a hang fire, rather than me punching paper.

Are there any common problems liek this, can anyone tell me what to do to correct this problem?

You might want to contact the previous owner and see if the same thing was happening to them and if so what they did to solve it.

I was the seller, it worked absolutely fine for me, it was reblued and heavily oiled after I fired it last.
My best guess is extra oil and gunk inside, possibly and ammo issue but I doubt that.
If everything is working fine, I would use some solvent or compressed air on the bolt/firing oin and re lube lightly with some gun oil.

let me know if you still have trouble, I stand behind the guns I sell. (I won't stand in fornt of them though!!!)
