Now that I know the TG ejector is the ststic system, I would suggest to you that you get yourself a plastic basket (small) and a couple pieces of cardboard and make yourself a catch basket. The pieces of cardboard or sheet plastic, what ever, are to make bankboards to catch the empties as you eject them. Make them tall enough and no matter how energetic you get in your bolt action, the case should not end up on the floor but in the basket. Wally World has the baskets in housewares, usually for drawer organizing, usually 3 for $1.00. Put all of this on a small towel under/beside the ejection port and the chances of a concrete damaged case get real slim.
