Mostly I shoot offhand ...but will shoot on the bench to 'checkout' the rifle (soft suede leather sand bags).
Honestly, I have hunted very little, but when I have hunted, all my shots have been offhand. Typically, at the range, I shoot offhand (practicing for rifle league or shooting in rifle league). There are a couple bench events in Rifle league, but most of the events are off hand. I should clarify, I haven't actually shot in Rifle league for several years...but I still practice like I will again shoot in a league someday, LOL. I do have possession of our sportsman club's Iron Rams, turkeys, ect.
Decades ago, when I go my first SKS and crate of ammo, I was at a friend's farm doing some recreational shooting, I tried Prone and used the SKS's bayo as a monopod...everyone laughed at me.
