I bought a Scorpion bench rest the other day, and it's alright. I shoot off of a plastic MTM shooting table, which has bowed a bit with age. Those rubber feet are slick on that plastic surface, and between the slick feet and the bowed table, sighting can be an adventure sometimes. I'm using the foam that is sometimes in pellet cases (JSB) as a field-expedient solution to give the feet some traction, but there has to be a better way. Any ideas?
