First, dont ever consider firing a charge behind a stuck bullet in any form. Ever!. Secondly is the wood dowel still in the bore? It cant stay in their while you try to push the bullet back, nothing but misery that way. If no wood inplace then listen to the people that said use a bore fitting rod. Under the circumstance you have a 6" good quality 5/16" bolt(not the usual big box Chinee extract) grade five. Its readily available, just make sure the end is flat and square. Wrap it with electrical tape in 3 areas so it cannot contact the bore and just passes in the bore with light contact. Then as someone suggested get a solid piece of oak or locust that will pass thru the frame and support the end of the barrel.. Get someone to hold the firearm in place and use a real hammer, at least 24 ounce. The wood can be locked in the vice jaws or placed across a bridge of the jaws or up on solid wood blocks, be sturdy. Little hammers in such a situation just break things. A 32 0r even a 48oz is not unreasonable. The bigger hammer will move things where the little ones deform things. One or two solid thumps should have the bullet against the wood block, then a few gentle taps with the frame held in hand should drop the bullet in hand. If you try to support the frame most other ways you may distort it if heavy force is needed. Clamping the frame in a vice is not the most supportive way to hold it. With the block you avoid twisting or rotating the frame in a vice.
Now if the wood is still in the barrel then you have to try a different approach. Pulling the barrel will be the safest one, if you need to or decide to pm me.
