have you ever seen a case like this ?

[FLORIDA KEVIN]

I would like to know if anyone can tell me what caused this deformation in a casing ? It was fired from a ruger .454 casull revolver and is I believe is the casing from either the squib round that lodged a bullet in the barrel or the round that was fired immediatly after ! the result was a bulged barrel and a trip back to the factory for my ruger !

It looks to be the second round, the one after the squib. I say that because the back pressure collapsed the case, which is about the only thing that could cause that in a revolver.

Glad you weren't injured and the only thing wrong with your revolver is a bulged barrel. A weaker handgun would have grenaded. I've seen them do that and it isn't pretty.

Hope this helps.

Thanks Fred !! I had come to about the same conclusion ! i just wanted someone with more experience to confirm it ! My only other thought was that maybe the powder was doing a slow burn in the case ! but I believe your analylsis is the correct one ! No i wasn't hurt ! more a tribute to ruger engineering than anything else! I"m just a little poorer (cash poor though I learned a valuable lesson !) I also think I am going to stick to published load data until i really understand the intricacies of reloading !I had one missfire and after it was cleared was still able to fire 36 rounds after the barrel was damaged !I didnt notice the front sight missing due to the use of a new scope ! i know guys i really screwed the pooch on this one !by the way the ruger was still giving better than 2" groups at 25 yards with a damaged barrel ! I cant wait to get it back from the factory !
