 They also realized that from 8 mm caliber upwards the rise of sectional density and penetrating capability of practical spin stabilized rifle bullets (bullets up to 5 to 5.5 calibers in length) tends to flatten out.This means that loaded with light, short and soft-nosed 8 mm bullets the 8×68mm S can be used on remarkably small game.Loaded with heavy, long and hard (solid copper alloy) bullets the 8×68mm S offers enough speed derived power to penetrate heavy and dangerous game.
