I never intended to build a high pressure gun,
Big cases allow lower pressures, IF the right powder is available,and the performance goals are reasonable, there is no intrinsic reason a 22-06 has to be a high pressure barrel burner.
This is where your philosophy may be flawed....
You mentioned that you want this to be a long range rifle to shoot 75-90 grain high B.C. bullets. The #1 thing with this criteria is to find a load that is consistent from shot to shot and has low standard deviation, most of the time with a cartridge such as this it happens at a fairly high pressure level.
someone(s) got offended on one of my previous posts when I called the 22-06 OVERBORE. to give you a more accurate assessment think of it as diminishing returns. compare a 22-250 AI (largest powder capacity I will ever use again) to the 22-06. you use a considerable ammount more powder in the 22-06 for very little velocity gain and a substantial decrease in barrel life.
