I have more sense than I have money, so I make a prototype rifle rest that worked so well I never did make a steel one. It takes me out of the sighting in new scopes and any new loads I work up.
I very rarely hunt with out my Bifur pod and will do testing after the rifle rest sight in with them.
I have a set of golf club shafts for prone, best use I have ever seen for any part of a golf club.
