[QUOTE="IllinoisBurt, post: 1847279, member: 35752"] Bullet velocity and case pressure are not always equal, so using a chronograph to guess pressure is only useful if comparing with published book loads for the same components. In this case the book is showing around 60k with a max load in the 2700 fps range depending on the bullet profile for 180 grainers with big game. Honestly given the primer flow is not happening with factory ammo, I would switch to a different powder that gets similar or better velocity with less pressure at max per load data. H4350 has always been a good higher speed/lower pressure propellant for 30-06 loads and will easily top 2700 with plenty of room to spare. There are a bunch of others as well. Take a minute to flip through the 23 loads listed for 180 grain 30-06 on Hodgdons website will quickly show which powders tend to fit the application better for pressure/speed combo.
