I have an Armor Metal Products Shooting Bench (they are out of Helena, MT) and it has served me well over the years but I do notice that if I lean into it my reticle will move substantially. I wonder if there is a more solid portable shooting bench available. I have looked at photos and descriptions of the BR Pivot Shooting Bench available from www.varmintmasters.net but they are quite expensive and I wonder if they were really any more stable than what I have. Have any of you used both products? If so what are your thoughts on the stability of both? I do not have a place to shoot with a solid concrete bench so I just set up my portable bench on some farm land. Thanks for any help, Rufous.
