There are several long posts on here somewhere about shooting sticks. If that's what he's looking for. Boulder, do a search and I think you will come up with tons of good posts.

Chapuis, I totally misunderstood the question. Also, I wasn't condemning them at all, merely stating that if he is simply wanting to test rifles OFF the bench {which is what I thought incorrectly was going on}, the sitting position is very accurate and it does not introduce
