Bugger - I load the 30-06 above SAAMI as you suggest. H4350 is your friend for max, temp insensitive loads.
Try this: 150 gr - 60.0 grains, 180 - 58.0 grains. I've not shot many 165's but simple extrapolation indicates 59.0 grains. You need to work up to those loads using a chronograph. Assuming a 24" barrel, stop at 60.0 grains or 3000 ft/sec with a 150, 59.0 grains or 2900 for a 165, and 58.0 grains with a 2800 with a 180.
You assume the risk here but I've shot those loads for years in many 30-06 with nary a stuck case, hard bolt lift, or loose primer pockets.
