[QUOTE="Glocktogo, post: 2567030, member: 1132"] The extreme spread and standard deviation will really come into play at 600 yards. At 100 yards you might have a very accurate load in your .223, but still have significant spreads. At 600, that same load will not print nearly the tight groups that a load with low spreads will. All else being equal, matching the load to what your particular barrel prefers is the best method. However, that doesn't mean it's an accurate load, just a load your barrel prefers. An accurate load will be accurate in most barrels because the consistency is there. Without a chronograph, you can't know the variables you're working with. As a competition pistol shooter, I'm looking for two things. Power factor and low standard deviation. I have to make the minimum power factor in order to legally compete. I don't want to go too far over minimum, or I'll be fighting unnecessary recoil. The low deviations ensure the gun cycles consistently and muzzle rise is repeatable, which aids in accuracy and control. [/QUOTE]
