We all know that it takes very little pressure, say a primer charge with no powder, to push a bullet out of the case just to get stuck in the forcing cone or barrel. Defective bullet? I suppose that is possible, but seems rather unlikely. The most obvious answer is often the best. What does the brass look like?

Edit: Someone will probably refute this theory any minute, which will cause me to swear off giving my opinion on the forum after my first shot of Kentucky's finest - until next time

Edit #2 - I went back and read the OP. Funny smelling Bullseye? Hmmm?
