DO NOT use a wood rod it will split on the bullet and jam the heck in it .
Use a solid steel rod as close to the bore as you can get it will not hurt the rifiling and beat it out.
Maybe that would work, but you run the risk of simply knocking off the head and leaving the body in the chamber; not to mention the possibility of slight damage to the rifling.. Not to mention that when struck, any rod (steel, brass etc.,) will flex and nearly ensure you'll need to repair the crown. I would stay away from any steel rod.. If you can find a brass rod, use that instead.. Thank God it's a dummy round.
I echo Jkob; take it to a gunsmith.. You run the risk of doing severe damage to the barrel..
The worst one I had was a fired case jammed in the chamber.. Even Cero-safe wouldn't budge it.. Had to remove the barrel and set it up in the lathe, cut off the head and set up the reamer.. It finally let loose after about a half-inch of reaming and with NO damage to the chamber/throat etc...
