The American gun companies at the turn of the century touted their composite steel guns could handle any of the new nitro powders. Sherman Bell's work also shows this to be true. I don't load low pressure smokelss because I think the barrels might come apart if I don't, I load low pressure to save the wood and the recoil is easy on my old shoulders. Pressure is pressure no matter how you slice it. Get a wall thickness gauge and be smart about it. Everything in life is a risk. Just learn to deal with it!
