My first concern is stock wood failure not barrel or joint. I just don't shoot any gun that I consider the barrels to be marginal in anyway. I have too many guns and too few extra fingers. As to pressure, I do try to keep 12 loads down to 6-7,000 psi. 5k loads are great but sometimes they do not do well in cold weather. All loads are as reasonable recoil as possible. By that I mean one ounce at 1100-1150 fps. 1 1/8 or heavier loads are just not needed to me. I have modern guns to handle heavy loads. Recoil cracks stocks not pressure so keep it reasonable. If your stock is loose get it fixed because loose stocks split easier than ones which the wood to metal fit is tight.
