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.
The US Army defines the maximum effective range of a .308 as 800 meters. The US Marine Corps defines the effective range as 1000 meters.There will be variances due to things like bullet weight, barrel length, etc.Generally speaking, bullets are no longer effective once they become subsonic, which happens at around 1000 meters with a .308. Maximum Range - 3,600 meters   Max Effective Range for a Point Target - 500 meters   Max Effective Range for an Area Target - 600 meters   source: Army FM 3-22. â¦ 9 Apr 2003 / 2-1 / PDF 27.
