So, shot skeet today in waterford with my 870, after 20ish rounds it would periodically lock up so I couldn't rack the slide, one time I had to slam it on the ground butt end first to get it loose, and the extractor tore the rim on the case. Anyone have any idea what my issue may be?
das edit: got back to the friends house who we travelled with, and he saw some rust pitting in the chamber. a bit odd for such a new gun, but previous owner wasn't good at maintenance. took a 20ga bore brush wrapped in steel wool and polished it right up ( he'd just done the same to his ithaca) and now its fine, so maybe a new shorter barrel will be ordered from remington soon
