Current 2209. My load workup was done with a fully calibrated GRT calculation, running at a calculated 62,000 psi, well within the limits of brass and rifle, even though over "book max" As I mentioned very important to work up and be aware of all factors when going above book max (which I dont make a habit of but the 6.5x55 just cries out for it). A previous modern 6.5x55 (a Heym SR-20) that I ran in the early '80s never got to this velocity with 130 as the tools (GRT) just weren't available then, and the ones we had like the Powley conputer (an internal ballistics calculator like a slide rule, and there was a paper based one too) were not sophisticated enough to fully explore anything above "book max".
