Detachable magazines

[kingcole2]

I see alot of magazines for 308 and 223 for tactical set up for chassis systems like MDT, AICS and so on. does anyone supply a magazine that works with different calibers such as 6mm remington, .243 win .30-06 and the list goes on.

cheers.

Mags are more about the rifle and the mag follower than cartridge. OAL's have to be very close too.
The Rem 742 etc rifle uses the same mag for all .308 based cartridges. The M1A originally came in .243 and used the same mags, as I recall.
Anything based on the .30-06 case length can use the same mags too.
The 6mm is kind of odd as it's based on the 7mm Mauser. Not many, if any at all, detachable mag fed 7mm Mausers. Suspect it'd feed through an '06 mag with an ~ half inch spacer though. OAL of a 115 grain 6mm is 2.825" vs the 3.340" '06.
