In choosing between the two lengths Faxon barrels with 5R rifling, using the same load how many FPS difference between the 18" and 20" barrel? The difference in weight is less than 5 oz, what would the extra two inches translate into in terms of increased velocity? Has anyone done a comprehensive analysis? Can someone who has both weigh in, or point me to some data?
