  I shoot BP Cartridge rifles.  I just received a Marlin 336 that was re chambered for 38-55.  Its is 'like new' in that its been shor ONLY 4 times and was then stored away for many many years. 
The barrel and chamber were done by a professional in AR, the rifle was set up for 38-55 and Starline brass BUT.......I did a stupid thing.   
I slid one of my hand loaded rounds that go into my single shot 38-55  into the loading gate and then attempted to lever it into the chamber.  WRONG!!!  Its a tad bit too long and I should have known this as my hand loads are longer than factory rounds.  My bad--my stupid. 
NOW WHAT!?!?!? 

 .  I can call a gunsmith tomorrow but I just wondered is there a quick fix to remove the round myself.  The lever WILL NOT move either way and I can clearly see that the very tip of the cast lead is sort of stuck. 
Anyway I really would appreciate any advice you all can offer.  Thanks, Jim Terrio.
