how deep is it into the barrel?
I had a buddy of mine come across this issue as well. He got lucky in the way that he apparantly didnt get powder into that particular rd. so with that said, the primer was sufficient enuff to get projectile into the barrel about 2-3".
I found some brass rods at a local hobby shop yrs back. I keep them in all my rifle case,s for "just in case". they have several diameters and there 3ft long. I picked up 2 that are .300 and another 2 of smaller dia. for smaller caliber.
I was able to get his projectile out but it did infact beat the holy crap out of the brass rod. the bullet,s tip did mushroom quite a bit but his bullets were hollow point.
If i did have to do it again?..... Id use a press as opposed to blows from a hammer.
