300 savage: I have bought at least 20 items from "Knothole Designs" over the last 15 years or so.
He comes in person to a lot of the gunshows in Montana and Idaho.
One of my friends did buy the portable bench in question from Knothole Designs and he really enjoys it - I have shot off of it a couple of times myself and it works, it is relatively cheap and rather sturdy.
I have owned 3 (three) different "portable shooting benches" for some time now and owned them since before "Knothole Designs" became known to me - or I would buy one of his.
Good luck to Boatammo in dealing with this situation.
Hold into the wind
