I've gotten into Trap shooting, and i've wondered what type of shotgun to get. Ive looked at both the Remington 870 express and the 1100. Fired the 870 at the local range(it was thier loaner) and it kept jamming after about 15 shots, i don;t know if it was the Shells or not (they were estate's). I have not Held or Fired the 1100 yet. but i was told by a friend that they are not good. someone clear this up for me?
