I have a two year old Remington 1187 that I've put over 2500 rounds through (sporting clays mostly). The first day I bought it, I ran a box of Winchester White box (WWB) through it and a shell got stuck in the chamber. I haven't run any more Winchester ammo through it since then and haven't had a single issue. Yesterday, I went shooting with family up at Shane's Sporting Clays. My sister brought a box of Winchester White box. I tried it again and again, I had another shell stuck in the chamber. The extractor ripped a slot in the shell and the shell stayed in the chamber. Mind you, this was after 2500+ rounds through the gun running flawlessly on all brands of ammo (except WWB). Subsequent rounds of other brands of ammo ran without a hiccup (200+ rounds). Has anyone else experienced this issue with WWB?
