Regarding the 5.56mm Mark 262 Model 1 ammunition, (77 grain Match), does anybody know answert to these 4 questions:

1) muzzle velocity out of standard 20" M16A4 rifle?
2) weight in grains of an "entire" loaded round (includes projectile)
3) Maximum effective range
4) Maxium range

I think this ammo is also known as AA53. Thanks, v/r dsg
