The way we shot the 22lr at 50m was prone, but no support. That meant only elbows and whatever else from your body contacted ground. No bags, sticks, tripod, bipods, walkers or wheelchairs... rules can be bent for those who can't bend.
1 shot at a time.
BTW Paladin was supposed to be in Peru by now, but there has been radio silence from his contact on the job. We should make it back this Sunday as I am speaking in a conference
