that's right= the old adage is 165 for hunting, 168 for match- you REALLY should do some READING on m14 match- there's a bunch of materiel out there and on the net that gives different powder charges, pressures, bullets, etc- the one by zediker comes to mind instantly- remember, this platform has been around for YEARS, and been used in national matches until recently- it's fully docmented as to loads, wearouts etc-
