I am wondering if anybody else is having a problem with their Remington shotgun barrels bulging after shooting steel waterfowl loads? Here is my particular situation: 1. Remington 870 Express Magnum: A couple of years ago I used the shotgun for 1st half of duck season; shooting 3" steel waterfowl loads with an "improved cylinder" choke tube. Towards the end of the first split I noticed the barrel was bulging behind the choke tube. Scrapped that barrel and purchased replacement for second split of duck season. Towards the end of the 2nd split, I noticed the new barrel was bulging behind the choke tube. I had an improved cylinder choke in the new barrel as well. 2. The following season I decided to give a Remington 887 a try. Shot 3 1/2" steel shells for 1st split of duck season using an improved cylinder choke tube. Same thing happened. Half way through the first split the barrel started bulging behind the choke tube. Remington shotguns are the only shotguns I have ever had this kind of problem with. Does Remington use inferior steel in their barrels? I don't get it! I have shot identical steel loads through my Stoeger 3 1/2" gun and 3" shells through my Yildiz gun with no barrel bulging problems. Has anybody else experienced barrel bulge with their Remington shotgun?
