and since we are talking about being stupid and locking up a barrel with a stuck bullet and the wrong ram rod, here's how you fix it.
so you have a stuck rod that can't mash on the bullet but only the bullet is sealing the bore. You can hydro the bullet out. Fill the bore with oil to an inch below the surface. Take a relatively tight fitting brass rod (.25 for a 30 cal, 3/8 for a 45, etc) and wrap the end in electrical tape. Put on muzzle and start hammering. Deal with the puckering arsehole. The E-tape jams on the crown and the rod pushes through. That seals the bore and now you are hammering on oil. That will transfer down to the bullet and put even pressure on it. It'll come FLYING out of the chamber. Flying. Ask how I know.
Then you can freely pound the delrin rod you stuck down there like an arse and clean your gun up.
If you were stupid enough to hammer on wood and that split-lock on you, you're in for a whole new world of pain to get that rod out.
