My Winchester SuperX2 will cycle the lightest loads. You have to really keep it clean however or it will start to not eject the spent hull. But I've run a case of light shells through it easily before requiring cleaning again. And my SX2 is chambered for 3 1/2". So if you just want to shoot 2 3/4" I would imagine the 3" SX2 would function just fine.Is there a 12ga autoloader that will cycle Winchester AA Featherweights as well as cycle 2 3/4" steel and/or hevi-shot waterfowl magnums?
