155 TMK @ 2850fps
1.0 Mil drift

As a bit of a side note, we hooked up the Pressure Trace and tested a mountain of things in the Creed. I had a suspicion about the operating pressure "range" in the Creed data. So we tested several powders and bullets against that theory. It fit quite nicely. What we found was that for every 75-100fps you gain, comes at the cost of 10-15,000 psi. So those who tell you they get 2900+ out of the 140's.... Well, easy to see roughly where their pressures are, and why they only get a few loads before primer pockets get loose.
My ballistic calculator didn't have the TMK's in it yet but the SMK's are 1.9 mils, no where near .6. I'm not going back into the overpressure debate, I'm getting right at 2800 with factory ammo and my reloads. I have several firings on my brass, and very few cases tossed for loose primer pockets on Hornady Brass. No sticky bolts, no stuck cases, pierced primers or any other traditional overpressure signs.
