Update: Tried shooting it out with small amouts of powder, no luck. Took it to a local gunsmith, and have it back. (He is going out of town). Tried the tube idea, didn't work. I am now noticing that the barrel has a short powder or patent chamber. (It's a Green Mountain barrel). Didn't think it did. Tube is hitting the shoulder. Tried to shoot it out with more powder. The caps are blowing the rag 0ut the barrel, but the powder is not igniting. I started with about 45 grains and I'm up to around 100 grains in there. (acumulated). The other night the 20 grains I was putting in did ignite. Does anybody know if Green Mountain barrels have a breach plug that can be screwed of ? Tried a .22 cal. brush, but didn't get it past the shoulder of the powder chamber. Gonna try again. Almost tried removing the breach plug myself. Don't really think I should. Can't turn out very good. But it may end up my only chance. Gonna hold of on that though for a bit. Not even sure if it is removable.
