I have a Shiloh Sharps #3 that weighs 12 lbs and has a shotgun buttplate. Loaded with 83gr 1.5 Fg and a 485 gr PPB about 10 rounds off the bench is all I can stand before getting head achy. Same with a 44-90 C Sharps built with the express type stock (straight and pistol grip). Its not the recoil so much I think...its the blast.

Never will understand how soldiers could endure the blasts of heavy artillery.
