Mark, thanks for posting that from the US Army Technical Manual. I still wonder if a very low pressure load can cause detonation which can damage a barrel. Hopefully the published low pressure 7/8 and 1 ounce recipes utilizing PB powder that generate 4300 to 5100 psi that I'm using in my damascus guns aren't adding any additional risk.
