Winchester Marine 12 gauge... anybody know the production date or any information about this gun? I bought this gun used earlier this year for about $270 in "good working/ cosmetic" condition. It is fully operational and very well cleaned and kept. I have taken it skeet shooting at least 5-7 times and shot 100-120 rounds each time (mosty 7 1/2 and 8 shot... a few slugs... maybe 15 at most; just to try it). it has proven fun and reliable to me so far. I have looked around alot on the internet and have not seen more than a couple like this. I just wanted some input on it. I really like it and think it is a nice shotgun. If it is old and "rare" I would prefure to buy an newer shotgun for skeet and keep this one stored. I would appreciate any type of feedback.
