I've heard a supossed expert say that mossberg was junk compared to remington, but realized he was full of crap about almost everything that came out of his mouth. So i'm askin you guys, what are the differences in these 2 (that apply to practicul use). what kinda life span and reliability can i expect from both??? "In Samuel Colt We Trust"
