One load from each of the 5 most-loaded bullet weights, plotted from the bore line to 1000 yards in ICAO sea-level air — measured from the muzzle rather than from a sighted-in rifle, so these curves compare the loads against each other and are not holdover figures. Compare these at your own conditions →
Weights are the ones with the most factory loads; within each, the load visitors compare most often. See every load →
