There's plenty of crazy stories on this thread, but that takes the cake. That sails right past madness into full on howl-at-the-moon raving lunacy.
It sounds worse than it really is.
Take a look at the data:
Bullet Weight (Gr.) Manufacturer Powder Bullet Diam. C.O.L. Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure
180 GR. SPR MT-SP Hodgdon H4831 .308" 3.285" 69.0 2851 48,500 CUP 73.0C 2966 53,200 CUP
Maxed out at only 53k CUP.
You can't fit enough in the case for an over-charge.
With IMR 4831, the pressures are a bit higher, but still plenty
safe for most rifles.
