Load Tuning For Long Range Accuracy

If all goes well, your groups should be flat like the above pic (the width of the group is due to wind), not like the pic below. Same group size but LR accuracy of the load in below pic will be horrid. Groups shot at 200yds.

Point well made.....and I agree now when I only look at the horizontal dispersement!

If you really want to learn how to tune loads, you will take a look at the video of Jack Neary's rifle tuning seminar. while Jack was doing the lecture for those of us shooting the 6mm PPC at 100-200 yards, the principles apply. I used the information I got from Jack to tune 6mmBR loads .223 rem, loads, .243 WSSM loads and more at various ranges.

There is also a program available that will allow you to DL video from YouTube if you want to keep Jack's lectures for reference.
