Raden,
That is a lot of force.
Consider this. When I push a pellet/slug through a barrel, and it's a bit tough, this is what I do. I put the cleaning rod handle on the floor, and use the barrel as a slide hammer. I pull the barrel up a foot or so, and with moderate force, slam it downwards. Sometimes I have to do that a few times.
What kind of pellet got stuck? If it's a Crosman pellet, it would be that hard. If it's a skirted pellet, it should be a lot less, but still a little bit of force will be needed. A Crosman pellet will fit extremely tight, and that would explain a lot, if it is that hard.
Crosman barrels are MUCH smaller in diameter in the lands as well as the grooves compared to other barrel manufacturers. They can be, depending on when made, up to 6 thousandths smaller. I spoke to Crosmans barrel engineer this afternoon at the Crosman All American Field Target Championship, and I was amazed and in awe when he told me the barrel dimensions. Much smaller than the other manufacturers by far.
Is it possible to get a picture of the metal deformation that you mentioned? I would be interested in what it looks like, I would like to think you did not do any damage to it. If the other barrel was the same, it could be a manufacturing defect. I'd be curious.
