Check to make sure the action is tight in the stock. Mine was not. Also, I loctited the rail and screws to the receiver. The rail only has 4 bitty screws holding it on, a lot less than what the rings have to hold onto the rail. The stock is pretty crap on these guns, if we keep our shotgun only law here in southern MI I will replace my stock next year and it will get a proper bedding job.
After checking the above, I was getting 1.25" groups with both Hornady SST's and Remington Accutips both 23/4" since there is nothing else out there that is actually in stock.
Just got this buck on Thursday morning. Shot between the eye and ear at 125 yards.
