Depending on the brass, IME, that`s not an absolute, but an indicator. Pockets loose the first go round, back off a couple grains..should be able to go 4-5 loadings or more with normal pressure. Again, an indicator.
If all`s well, enjoy the load.
So somewhere in between the 2-5 loadings it's OK to shoot a high pressure load? As stated, there's no free lunch.....high velocities = high pressure, even if it's not obvious.
