Bottom line is, IMHO, if your primer pockets are holding then your brass is holding up to whatever pressure is on it. IME, If you're not blowing primers you're a safe distance from catastrophic failure and if your pockets are holding up to 5 or more firings then you're running safe pressures whatever they are.
If your velocity is within reason then you are correct.
If your velocity is over what is listed in pressure tested data your brass is holding, but you are placing yourself in some form of risk. If you are a few hundred fps over pressure tested data you are in imminent danger.
More than just the brass there is the matter of the action taking the strain...year after year.
The reason I am making noise here is I believe elkaholic has a cartridge about the capacity of the 300RSUAM. Yet he is 250fps over what normal speeds in that cartridge.
Worse than that he is 100fps faster than what is recommended in the 300Win magnum with IMR-4831 by 100fps!
I don't think Elkaholic is stupid or anything else derogatory. I read a few of his posts and he seems totally on the ball.
After the 416 incedent and another friend blowing up a rifle because he could not "read" the pressure in his rifle in the conventional way I bought pressure testing gear.
The truth is you don't need pressure testing gear you just need a chronograph and need to know the cases capacity and you are set.
But that is enough.
The only other guy to raise a red flag was BartB....So that is me done on this subject.
I wish elkaholic well and safe.
