Only a fool doesn't work up in some form or fashion.
There's no substitute for rounds down range...
A load manual is a good general consenous, beyond that, it takes trigger time..........
This from the person who so fervently extolled the virtues of what did you call it..... OCW
Accuracy loads are not always tested by shooting a loaded cartridge downrange, many are shot in a pressure barrel and the load listed produced the most consistant pressures. Take it with a grain of salt, I have had accuracy loads from both Nosler and Sierra that have produced excellent accuracy and others that have not faired so well. I ideally try to go for a load density greater that 80% but that does not always produce the best groups. I decide on bullet then start with the bullet manufacturers data unless I can't get acceptable accuracy then I go to the powder manufacturers data. That being said I also like to use the Lyman manual as an unbias data source for reference.
It's obvious, from your comment, that:1.) you don't know what the OCW principlesmean, and, 2.) you don't know the meaning of the OCW principles.....
OCW stands forOptimal Charge Weight. It is a load work up system that tunes your load in a quicker and more efficient manner than what is accepted by the masses asthe norm. OCWload principles staywithin the confines of published load data with regard to minimum and maximum charges.Optimal does not mean Maximum. OCW load principlesdo not address the whims of speed junkies, it often times finds a powder charge that is below anything maximum. OCW load principles address the mechanical and physical properties of that particular rifle barrel with regard to how barrel harmonics affect that particular barrel.
A large factor in successful OCW load work up is an informed choosing of powder and bullet to yield a workable load density and accurate flight of a bullet with adecent BC. As a side benifit of doing things this way the load will likely be extremelytolerant of Pressure Variences....somethingheld in high regard by the fans of "extreme powders".
In my opinion it works betterand more economically that the standard "add a half grain and see what it'll do" mantra........
