My son has a bt-100 that he is shooting.The gun was bought used but has not been shot much at all.It has a problem of not wanting to unlock to breakdown sometimes after it has been fired.The top lever wont move and it you have to work it preety hard to get it to move to get it broke down.The gun still locks up really tight and the top lever is all the way to the right.I would like to know whats causing this and what the fix is.All info is greatly appreciated.Thanks joel courtney

More tham likely your shells(hull) are sticking in the camber. What kind are they. Steel based reloads and cheap shells did that in mine.---Matt

I had that problem, years ago, with a bt-99. A small wafer of steel that actuated the ejector had seperated from the rod. It wandered around inside the gun, until it lodged in a spot where it caused just such a problem. I'd remove the stock and clean out the insides, really well, just in case.

I dont think it is the shells.He is shooting sts hulls with 1 oz loads loaded in a ponsness warren press.he also shoots factory sts loads.They are not sticking in the chamber.

Sounds like the firing pin is not retracting.

Is the a mark on the hulls ... from the primer to the rim when finally opened?

If the top lever is difficult to move to the right, have you checked to see if the locking block is getting wedged too tight into the mating goove in the monobloc? The groove may need to be cleaned out & a little Triflow dabbed on. John

Your statement, "The top lever wont move and it you have to work it preety hard " indicates there could be something wrong with the top lever. Check to see if the top lever dog is broken.

Just possibility, the previous owner might have gotten caught shooting in a rain storm causing the top lever spring to rust. Try spraying a very little oil around the bottom of the top lever.

Another good possibility might be Art's in MO the link is above. He is the man when rebuilding BT's. He might help as well.---Matt

take the stock off, lubricate the rusted parts of the lever mechanism and let us know
