[QUOTE="Bravo 4, post: 1531132, member: 8873"] DDB TX, The Army comes up with their maximum effective ranges by meeting two criteria, probability of a hit (accuracy of the weapon/ammo combo) and terminal effects on target. I pretty much do the same thing, is my rifle capable of a high percentage shot and is the bullet going to have the effect I want when it gets there. Example: my .338 RUM will not shoot any high BC bullet to my desired accuracy, pretty much puts everything into 1.25-1.5” groups at 100. Not even really worth my time stretching it out. It has the “energy” (minimum velocity 1800 FPS and your 2000 fpe with a 300 grain Berger) to take an elk where I hunt to out past 1300 yards. I wouldn’t even attempt that with this rifle because the probability of a lethal first round hit (even under idea conditions) would almost be what I would consider luck. The load I’m currently using is with a bullet that has no where near the BC but groups under 1 moa out to 800, where it also runs out of the “energy” that I find sufficient in cleanly taking an elk. So under favorable conditions 800 is the max effective range for that rifle/ammo. Now just because the rifle is capable doesn’t mean the shooter is. Like I always say in my weapon classes, the number 1 factor in the max effective range of a weapon system is the nut behind the trigger! [/QUOTE]
