Hodgdon’s data is very watered down. Compare their data for the 7mm stw to what Simpson did with it when he developed it. Totally lame comparatively speaking.
Funny you should mention that...
I have done some pretty in-depth research the last few days. And I have concluded that no one really has a clue. The only data anyone can give you is for the specific test weapon they used to produce those results... And that is only for that specific lot of powder of that brand... That specific lot of bullets of that brand... And that specific lot of brass of that brand... Fired by that specific lot of primers of that brand... With that specific pressure testing device.
Change any one of those variables and it's an absolute crap shoot.
The absolute best you can do to be certain your loads are safe is to find a starting point and work your way up and look for physical signs of pressure. Everything else is just a semi-educated W.A.G.
