[QUOTE="Good, post: 418111, member: 18866"] I feel that a low SD and single digit ES will be an accurate round at any distance provided everything else remains the same. As long as you don't have scope movement, a different hold on the gun, all seating depths are the same, etc., then that will be an accurate round. I'm not very experienced, but as far as I can tell, consistency equals accuracy. Of course there are always exceptions to this. There might be a bullet that just absolutely likes a particular velocity range. The ES might not be the lowest, but the bullet just likes that twist rate, velocity, and everything else that is in the package providing for an accurate load. It is very likely that this round might be more accurate than the round with single digit ES. My job is to find the most accurate round, whether that is the round with the lowest ES and SD or not. Right now, we're digging the 208 AMAX with 48.4g RL17 out of a pretty much stock Rem700 .308 topped with IOR Valdada glass. Last time out it shot 4 rounds at .8" at 200[B] meters[/B]. It shot really well at 750 and 800[B]yds[/B] also. The local range is in meters but only goes to 500. There are 750 and 800yard targets set up further out though. But, most people are finding their nodes at 46.5ish grains with this round. [/QUOTE]
