I finally had access to a chronograph this weekend for the first time in almost 10 years so I got a chance to run some numbers. All loads were developed based on accuracy, velocity was unknown until yesterday. I figured I would post them so people who have the same rifles can get an idea.

I was surprised with my 7mm 140gn load, I always assumed it would be around 2800fps. 168gn load measures 3/4moa even with that velocity spread, go figure.I was expecting more from both 308 rounds. The AMAX round is pretty slow but just about 1moa for me and I expected more speed albiet not the most accurate in my gun, my PTR doeskin seem to care for 150gn bullets.
