Some may argue, but they are usually debating from a scientific , text book debate. But I am here to tell you that many 338's I have set up with 300 gr bullets, (SMK or Bergers) would shoot the same size groups at 200 as they did at 100.Sometimes tighter. I have a set of targets on my bench from a 338 EDGE right now to prove it. With several load variations and seating depths the rifle was shooting just under an inch, down to .6 at 100. So I felt it was time to test the two best loads at 200. The .6" or .6 moa load at 100 shot .431" or .235 moa at 200 yards. I shot a two more groups at 200 that were all under 1/2 moa to confirm. Then took it to the field for longer shots. The rifle held 1/2 moa 3 shot groups at several distances out to 1500 and shot very well at 1700 and 2077 yards.
Sometimes I think it just takes over 100 yards to get a bullet to stabilize and find it's path. My thoughts are just from what I have seen with my own eyes.
Have you ever seen this video about pitch and yaw?
Watch the yardage.
