I have been shooting clays with some good friends using an old Remington 1148 (made in 1957) for the past few years. The old gun runs like a top, but it's been in the family for a while and shooting 2k shells per year through it will eventually wear out parts that will be hard to replace. On top of that, I'm just ready for a new shotgun. My local club runs shotgun side matches after USPSA shoots sometimes that look pretty fun. Therefore, I'd like a new auto that is 3-gun capable.
Here is the rub, the auto must run at least 99% on Walmart-type bulk cheap shells. My buddies and I all shoot each others guns and ammo, and sometimes one of the guys will find a deal on shells and buy a ton of them. We subsequently end up all shooting the same stuff. It wouldn't be the end of the world to use slightly more expensive ammo, but it would definitely be inconveniant.
Anyway, I have an older Colt AR that I can probably get $1,000 for at the next gun show, so that plus a few bucks is my budget. I've searched and read this forum as much as I could and it looks like a Winchester SX3 has a light piston option that might work. I tried one on at a local shop and if fit well. A Remington 1100 would probably be my first choice, but they don't fit well and I've never been able to hit with them. So I guess my questions are: Will a Benelli M2 run on light loads? One of the guys I shoot with has some version of a Benelli that is very inconsistent with the shells we use. Is a Browning Silver close enough to the SX2/3 that it can be used? These are the guns I've found around the $1K mark. Is the Mossberg 930 proven enough one way or the other? Any others I'm missing? Thanks much.
