Extra Barrels


Recommended Posts

Absolutley, wouldn't be much good without it....

As I am new to this, wouldn't the bolt mechanism for a 30-06 still work for a 300 win. mag?


As I understood it, the only thing you can't do is go from long action calibers to short action calibers or say I have a 30-06 I can go 300 win mag, but I can't convert to 300 wsm or any of the short action calibers.... Does this make sense?

Well, almost.

The case need only fit the chamber, which is obviously part of the barrell.


Different calibers, long and short action alike, use different bolt head sizes.


For example: 300WM and 7mmRM are the same bolt head.

30-06 fits 25-06 and .270.

22-250, 243, and 308 are also interchangeable bolt heads.


But bolt heads are not the only issue when changing barrels on a repeater. The magazine must also accomodate the cartridge cases in order to feed properly.


In short, it goes something like this.


1. The barrell must be chambered for a specific caliber.


2. The bolt head family size must match.


3. The magazine must be able to accomodate the case.
