    there are differences between the data from different manuals because the different data was cooked up using different components. use data from the manual that best matches your set of components and develop your load.

    Well, the starting point starts with the bullet. Just because a bullet is the same weight does not mean the pressure will be the same as all the others of that weight.

    Some of those bullets have more surface area touching the barrel, some have stickier metals that grip the barrel, some are solid which make them much harder which react differently than say a Sierra Matchking.

    You really need to go by the manufacturers recommended info for the type of bullet you are using.
