Question on Navy sniper ammo

I've been told That some Navy snipers us the 300 WIN MAG. Does anyone know the ballistics on such ammo. I've been told it's very accurate stuff.
A lot of info can be found here A-191 Cartridge Development - Press release

Does not give the charge of Re-22 but if memory serves it is around 72 gr (work up to this) with a 190 gr Sierra. The navy is stretching the 300 WIN MAG out to 1500 now using the 220 gr Sierra as a less costly change than going to the 338 Lapua.

I've not done enough research on the propellant to even give an educated guess.

Several years ago I shot a 500 yard Match with a guy shooting the Black Hills version of the A191 and it shot very well at 500 yards.

Hope this helps.
