Thanks for the info. I think Skeetx summed it up in his first sentence with the operable wording being "direct". "Velocity and pressure do NOT have a direct correlation." I believe there is a correlation between pressure and velocity. However there may not be a exact correlation. If I was to take two shells and load them exactly the same except for powder charge and shot them through the exact same barrel the one with the higher pressure would have a higher velocity. Correct? Generally if I am looking for a 12 gauge shell and want a lower pressure but the pressure is not listed on the box, I can look for the lower velocity shells and this will give me a good idea that they are lower pressure. I typically shoot shells with a velocity of less than 1150 fps in my 12s which are all fluid steel barrels in good condition with good wood on the stock. Please correct me if I am wrong. I am always open to learning new things.
