[QUOTE="blicharski1989, post: 826055, member: 69633"] That is a pretty good extreme spread. I would confirm that the actual velocity measured is accurate within reason. Try changing primers, make sure your COAL is consistent, back off the load a little bit? 3200 FPS is a pretty stout load. Some powders shoot best at max, some run best slightly below max from my expierience ( limited) New Barrel? how many rds through it? signs of fouling? What distance was the Chronograph from the muzzle? Some chronographs require 15-20 ft from magnum loads to get accurate readings [/QUOTE]
