My technique may raise questions of safety, but it works for me. I set up my portable shooting table, place the gun barrels in a sandbag rest, crouch behind the table, cup the gun butt in my left hand, duck my head down as far as I can, reach up and fire with my right hand. The gun will jump a wee bit, but my left hand takes most of the recoil.
I do this with guns after subjecting them to careful disassembly, cleaning and inspection. I wear magnifying glasses while doing all this to make sure I don't miss anything obvious. I may be throwing caution to the wind with this procedure, but I like to think I approach the whole thing in a serious manner.
