Big uncle good post...I just posted to someone asking about shooting sticks and bi-pods and the use of them...told them that using their sling will give them a good steady "rest" out in the field when game is coming in hot and fiddling with a stick or pod isn't an option...to make their using the sling second nature at the range.Then if they want too try a pod or stick do so. I sight in with a bench but practice off hand(may not be correct term..but one I use)...not always are we hunting with a shooting rail...
