Maybe if you were under their load data
I'm glad to see they added the '06 and 280 Rem to the load data. I hope you're not running too hot to get a few extra fps,
I don't know why you would even think that?
I am using their load data.
There is no way I'm running too hot.
Here is the Hodgdon data for the 30-06 using S-F.
150 GR. NOS BT Hodgdon Suprform .308" 3.250" 60.0 2850 43,100 PSI
65.0C 3072 53,000 PSI 155 GR. SIE HPBT Hodgdon Suprform .308" 3.225" 59.0 2843 43,400 PSI
65.2C 3125 58,800 PSI I could go to their COAL length and cut my powder by two grains and achieve the same results. My longer COAL allows me to load more and still be within pressure limits of the 06.
In Hodgdons 150 grain load data there is 5 grains and 9,900 psi difference between the starting load and max load. Thier max load is only at 53,000 psi.
Roughly, but I think a good estimate, if I take that 9,900 psi difference and divide by 5 grains I come up with 1,980 psi per grain of powder.
The difference between starting and max load.
Those two extra grains of powder add me 3,960 psi to 53,000 psi for 56,960 psi in a cartridge designed for 60,000 psi.
Again, add to the fact that I have a longer COAL my pressures
would safely be lower than that.
It's obvious I'm GTG.
