overmax
The 7 Remington Magnum is the LAST cartridge (other than the 243) that I would run at velocities exceeding loading manual maximums. The loading companies have found that the 7 RM pressures for a given load will have a wider range than most cartridges.
In other words, if the 7 RM is loaded to 60,000 PSI, the maximum pressure that load will generate will be higher than say, a 30/06 loaded to 60,000PSI. Therefore, loads for the 7 RM are held to a lower average pressure.
I can never understand why someone will sing the praises of a ceratin cartridge and then use over maximum loads for that cartridge to demonstate it's excellence. If the cartridge is so damned good, why do you have to run it so hot? Why not just go up to a 7 Dakota or a 7 Weatherby?
