Minimum OAL for .308 in a AR10?
Hi guys, I've just finished loading a bunch of .308 for my AR10 and I had a old box of Sierra 125gr spitzers, was wondering since the OAL on these is only 2.67" is that too short to be fired safely from my semi auto?

SPECIAL NOTE ON CARTRIDGE OVERALL LENGTH “COL”
It is important to note that the SAAMI “COL” values are for the firearms and ammunition manufacturers industry and must be seen as a guideline only. The individual reloader is free to adjust this dimension to suit their particular firearm-component-weapon combination. This parameter is determined by various dimensions such as 1) magazine length (space), 2) freebore-lead dimensions of the barrel, 3) ogive or profile of the projectile and 4) position of cannelure or crimp groove. |

Put a few in a magazine and see if they feed-chamber properly. ??
