Was wondering if anybody has experience with anything like the Specter shotgun shell holder? I have the ATI screw-on holder on one and like it very much but would like something I *could* put on the sporter without drilling into the stock. Currently have a rather [censored] uncle mikes sleeve-style shell holder in the grab bag, but its...not impressive. Of course, price is always important but not the only factor. Looking for an ite, that can be depended on.
