Yes, tripod would work too. Being upright allows you to absorb the recoil by flexing. I like sitting at the bench but the pounding is brutal in the typical low position. My shooting sticks let me sit up straight about like a standing position with tripod. It makes a world of difference!

For heavy slug loads I also use a piece of folded carpet between the butt and my shoulder. It also hangs over my shoulder down my back a bit so it stays in place. Kinda cheap and cheesy (redneck solution) but it works well. Maybe I should duct tape it in place!
