When a 7.62x51mm NATO cartridge is fired in a .308 Winchester rifle, the marginally totally different dimensions and strain curves of the NATO spherical can push the strain past what the rifle was designed to face up to. This strain overload, even barely, can result in a cascade of issues.
Extraction Troubles
One other consequence of improper ammunition utilization is the chance of extraction points. If the strain contained in the chamber turns into too excessive, the brass casing may develop excessively and turn out to be firmly wedged in opposition to the chamber partitions, making it practically unattainable to take away. This case may cause jams, forcing the shooter to take away the caught cartridge.
Catastrophic Failure
Catastrophic failures are probably the most feared chance. These contain important injury to the rifle and, much more importantly, the potential for critical harm to the shooter and people close by. Such failures can embrace the bursting of the barrel or a whole failure of the receiver.
Lack of Accuracy

Even when no instant malfunction happens, firing the mistaken ammunition can negatively influence your taking pictures efficiency. Totally different ammunition varieties have totally different ballistic profiles. Mismatched rounds will change the purpose of influence and trigger grouping errors.
The Actuality of Twin-Chambered Rifles
Rifles Designed for Each Rounds
Amidst these potential hazards, it is very important acknowledge that sure rifles are particularly designed to securely chamber each the .308 Winchester and seven.62x51mm NATO rounds. These are sometimes constructed to extra strong tolerances and are clearly marked by the producer to point their compatibility with each forms of ammunition.
Following Producer’s Tips
Nevertheless, even when such a rifle is on the market, it’s important to all the time adhere to the producer’s particular pointers. These suggestions are there for a motive, and they need to by no means be disregarded. The producer’s recommendation is predicated on the design of the weapon.
