Quick Answer
The 9.3x62 and .300 Win Mag differ in case length, bullet diameter, and recoil, affecting terminal ballistics. The 9.3x62 has a longer case, a larger diameter bullet, and generally less recoil. This results in more expansion and penetration.
Case Length and Bullet Diameter
The 9.3x62 has a longer case length (2.49 inches) compared to the .300 Win Mag (2.01 inches). The larger diameter 9.3x62 bullet (0.308 inches) also contributes to its unique terminal ballistics. A larger diameter bullet typically expands more, but also offers less wind deflection, making it suitable for hunting larger game at shorter ranges.
Expansion and Penetration
In terminal ballistics, expansion is critical for effective hunting. The 9.3x62’s larger diameter bullet expands more than the .300 Win Mag, resulting in deeper penetration. For example, the 9.3x62’s 286-grain bullet can expand to 0.55 inches, while the .300 Win Mag’s 150-grain bullet expands to 0.35 inches. This expansion results in faster and more efficient killing of larger game.
Recoil and Hunting Implications
The 9.3x62 generally has less recoil than the .300 Win Mag, due to its larger case capacity and longer case length. This makes the 9.3x62 more suitable for hunting larger game at closer ranges, where the shooter can control the rifle effectively. In contrast, the .300 Win Mag’s shorter case and smaller diameter bullet make it better suited for longer-range hunting, where the shooter needs to compensate for wind deflection and bullet drop.
