I initially edited my above post and took out the pressures I had put in and replaced the hard numbers with the term "moderate". I did this because we don't know exactly what pressures are proper for each individual old gun. I do shoot lower pressure loads in most of my guns because there is no reason to use a higher pressure with today's component choices. If pressure was a non-issue then we wouldn't have pressure limits. Too much velocity, mass of ejecta or pressure can all be deleterious and need to be considered. I see some people shooting high velocity and low to moderate pressure loads who think they aren't doing any damage to their gun because the pressure is under 10K psi. We have to remember that all of this is a balance and there is no free lunch.
