308 maximum effective range
It is accepted that if you do your job and put the bullet where it counts, you can count on the .308 to do its job and incapacitate the target. The US Army preaches an 800 meter maximum effective range for the .308, the USMC preaches a 1000 yard (915 meter) max effective range.hile we have made hits at 1000+ meters with the .308, we tend to agree with the Army and indicate that 800 meters is about the max limit for RELIABLE hits in all but extreme weather conditions.
