Floyd, I can relate my experience only to you, but would URGE YOU TO CONSULT A GUNSMITH TO EXAMINE YOUR GUN FIRST. I have used 2 1/2 inch shells imported from England that Cabela's carries that have 6000 lbs pressure according to the box. I have shot these in my damascus gun without problems, but every gun is unique. These are expensive, about $11 per box, but if you don't reload maybe a good option. I can't remember the exact name of the shell, but Cabela's should be able to help you. Good shooting. David R
