Traditional method, start low and work up your load... once I hit pressure signs, or a full case, I usually back it off
and then pick whatever was the most accurate load tested.. then chronograph it to see what the velocity is..
as Smokepole eluded to....there are rifles that will not take certain "max loads" listed in load manuals...
It also works in reverse. I had a 7 WSM that I found a really accurate load for with 160's. Chronoed it and saw that it was shooting at 7-08 speeds.
