A buddy of mine from work has a FAL and is trying to duplicate the 7.62x51 NATO load for it. He will be using the 147 grain FMJ's and Lake City Brass? What powder/primer should he use and the COL for the round? What is starting and max load? I believe the NATO spec velocity is around 2700-2756 fps? Thanks Esox357. | ||

the spec is 46 grns of wc846 (which is the same as I4895 from a burn rate perspective) for 2750 fps with technically 146 grn bullet Mike Legistine actu quod scripsi?

I have found that with a 150gr hunting bullet usually Nosler or Sierra that 42gr of IMR 3031 hits the same place as Military Ball in a HK 91. I used either CCI or Federal primers, in LC brass. DOUBLE RIFLE SHOOTERS SOCIETY | |||

esox The powders used to load mil spec ammunition is not canister grade. Probably close. Ray Arizona Mountains | |||

The specs quoted are straight from the Armory Ammuniton data sheet. The reference to burn rate being similar to I4895 is that there are some loads in the data sheet that last the two powders as substitutes for each other Mike Legistine actu quod scripsi?

Military power is always different from commercial powders . It's the law . Some can and are substituted for each other as far as loading or burn rates is more accurate. When I worked for Hercules Powder ( Formulating explosives ) YEARS ago !, Only the FBI CIA NSA , were allowed to know specifics of manufacture . In case they were ever abused they could be traced . Hence why some powders have different trace elements to them while others don't . Shoot Straight Know Your Target . ... | |||

M-80 load uses 46gr. WC846 (ball powder and NOT stick powder like IMR-4895). NOTE: THIS IS A CORRECTION FROM MY PREVIOUS POST ABOVE! (Which I have deleted). BL-C2 is the closest commercial equivalent to WC846. H335 is the closest commercial equivalent to WC844. I repeat.... the closest commercial equivalent for the M80 7.62mm ball load is BL-C2. But reduce loads and work up! I prefer IMR-4895. Not the powder used to load the military M-80 cartridge.... but better accuracy. A PDF document of TM 43-0001-27 is available online here: ARMY AMMUNITION DATA SHEETS SMALL CALIBER AMMUNITION FSC 1305 The M-80 7.62 ball load is in Chapter 11 on page 114 of this PDF document. PS - The M-852 7.62 Match cartridge is described on page 123 of the PDF document. IMHO, I think this is a better route to go than trying to reproduce the M-80 cartridge. The Sierra 168gr. MK is a bit more expensive than the Winchester 147gr. bullets with open base, but the accuracy is MUCH better. | |||
