A friend at work picked up a rough old 500 at a gunshop, he wants to go hunting with me one day this spring. Anybody had any luck with the older 500's, i think he said it was an accu choke, but not sure. Somewhere I have a turkey choke for a mossberg, if I can find it I'll give it to him. Think we will start with some turkey thug #6, cause I have a few boxes of them.
