It is indeed a 10 ga. and it is chambered for 2 1/2" shells after having 2 different dealers look at it, will have a competent gunsmith look at it later. Overall condition they say is nice. I didn't notice before but the stock and foreend is checkered, just filled in with dirt and grease. Overall a nice piece and as stated before it locks up nice and tight.
thanks again
Get some acetone and a toothbrush and that should take care of the embedded grease and dirt in the checkering.
BTW: Beware of Cowboy Action Shooters as they've never seen a shotgun with over 18" barrels they liked!
