I've got a Remington 870 Marine Magnum that I've had for several years now. Some time ago (~3 yrs) while cleaning I noticed lengthwise gouges in the bore (entire circumference) that obviously were caused by firing some kind of shot through it.
I don't know, nor am I suggesting that these lengthwise gouges are a problem, but I'd at least like to understand what caused it.
I probably have shot some steel shot through it years ago. Maybe that did the "damage"?? I was sure to check the manual and the barrel markings for any type of ammo warnings but have seen none.
Any ideas here?
