WEIGHING BULLETS TO REDUCE VELOCITY VARIATION AND IMPROVE ACCURACY

223, 5.5 gr Titegroup, 40 gr bullet, 2063 fps, 53 gr bullet, 1784 fps, delta fps/gr, 21.5

22-250, 5.5 gr Titegroup, 40 gr bullet, 1857 fps, 53 gr bullet, 1622 fps, delta fps/gr, 18.1

22-250, 8.5 gr Titegroup, 40 gr bullet, 2418 fps, 53 gr bullet, 2137 fps, delta fps/gr, 21.6

The largest delta fps/gr of bullet weight is 23.4; a bullet weighing 1 grain more than another would go 23.4 fps slower.

Weighing, segregating, loading and shooting bullets into .1 grain classes reduces delta fps to 2.34 fps.

In .5 gr classes, delta fps is 14.0 fps.

Weighing bullets and segregating them into small classes won’t improve accuracy.
