I agree with most of what you said. However a 6 pound rifle still has a trigger pull greater then half the rifle weight which on a fast shot makes for a pulled shot. In addition to this you build confidence in your shooting abilities and your rifles on the bench. Here being beat to death defeats the goal. Your point about shooting in hunting positions after the rifle is sited in is excellent. I tell this to my customers all the time. Lots of them seem to forget that in the woods or where ever, we do not have shooting benches and sand bags. To forget this fact will result in lots of wounded, missed and lost game!!!!
