I have a manual, modern reloading rev.2, that shows pressure as well as velocities for max loads. When looking at the .300 win mag loads, many of the MAX never load above this amount loads were actually below SAAMI max pressures by almost 4k in some instances. Same with the .308 load data, most of the loads were 2-3k lower than the max SAAMI pressures. Why is that?
If the max SAAMI pressure for .308 win is 62k psi, why only give load data that goes up to 59 psi (some max loads were as low as 55k psi)? Why not give full max loads and put a waring that you might blow up a gun that isn't in top condition on them instead? You would bet that the manufacturers make their guns to handle the max pressure for the caliber, why can't I find load data that will let me do that?
