Something to think about...75% of the ammo I tested has chamber pressure above 50,000 psi. For those of you worrying about chamber pressure...if you shoot AP you are in the 60-61k psi range for some of the "warmest" ones..57k or so for the weaker ones.
You have been teasing us for more than a year, that you have actual test data on the chamber pressures and port pressures of commercial ammunition. Lets see that rabbit. Pull it out of the hat.
