The Frankford Arsenal did a study on high-powered rifle rounds and found that the being off a few grains did not really have much of an affect on accuracy. The biggest change was from different lots of primers and different brands of primers. This is in the original NRA Handloaders Guide. This study was only done with high-powered military rounds.
