This caliber or cartridge ranking illustrates how a specific rifle caliber ranks amongst others in terms of its ballistic performance (E0 = bullet energy at muzzle). The figures shown are the averages resulting from load data with all suitable bullets and powders for this specific caliber. Loads rated well by our community get weighted more when calculating the averages. The performance of a specific load (specific bullet, bullet weight, powder, and powder weight) can deviate from this average. It starts with the tiny .17 HMR and ends with the "hammer" .50 BMG.
Any surprises in the ranking?
