Hey snakedoc no problem. Those Grand Slam rings are very solid and appear to be well made rings. I have held a set before but never seen them mounted up or in use. Sorry I don't have much stock advice for you, still running the factory stock on my Stevens which is the same as the Hog Hunter as far as I know and I'm routinely getting sub moa, near half on a good day. I will swap it out eventually, probably for a Choate Tactical. I really like that design.
