7.62mm Military load data

 


7.62mm NATO
A detailed list from TM 43-0001-27 "Army Ammunition Data Sheets Small Caliber Ammuntion"

MASTER PO'S DISCLAIMER: The following is for informational purposes only. DO NOT USE THIS DATA TO REPLICATE. Burning rates for IMR 4895, specifically, can drastically change from lot to lot since this data was developed.

Many of these powder loads have been replaced by a new Olin powder sometime in the mid 1990's, specifically the M852 and M118 cartridges. Master Po is working on the specifics of this change.

NOTICE: The possession of any 7.62mm NATO Armor Piercing cartridge has been deemed unlawful. Master Po has seen this stuff at shows in the hands of dealers and collectors. Caveat Emptor!
