Also had to laugh at the "lighten the knock-down targets" as well. The US Army was converting FROM the M-14 in .308 to the M-16 in .223 back in the late 60's early 70's. We shot at targets at 300yrds, while I believe our fellow Marines were using .308's at 600yds? Anyways, ask some zips if they felt the .308 wasn't sufficient to knock them down
