Today I had my 12 gauge Remington 870 out and i shot it and my barrel swelled up and when you look down the barrel you can see a groove. Anyone ever have this happen and will Remington prehaps send me a new barrel since there was no foul play.
Guns are fired with a heavy "proof round" before they leave the factory..If that didn't blow the barrel out, then I doubt that an ordinary hunting load would do it either...I would suspect a barrel obstruction as well.
After the first shell miss fire, they should have been put back in the box, on the kitchen table, and a phone call Monday to the Manufacturer of the shells.
Why would one continue to shoot shells that are defective.
It is a very good chance when the squib went off if left the load or at least the wad in the barrel,, perhaps more than one load or wad since you did it three times, when you shot the next good round you had an obstructed barrel and it bulged. You are verry lucky it didn't blow and injure you. I highly doubt Remington is going to replace the battel because the bulge is not of their doing, it was your doing. When ever you have a squib load you should emoty the gun and make sure the barrel is clear before you try to shoot it again. You are one lucky man, I know you don't think so but you are for sure. Gives me the Willies thinking about what could have happened!
