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...

I have a batch of 223s....and I don't assume a load that is good in one of them, is good in another one...

Like what I have been playing with for this varmint season...

a Rem VLS will pop primers, on loads that function just fine and are the most accurate in a Ruger VT.

each rifle is an entity onto itself...

I heard that somewhere... whistle
