Баллистика от Тони Вильямса из "заслуживающих доверие источников".
>Some interesting data has emerged from a reliable source on the ballistics of the M855A1 EPR. I thought I'd post it here, to stimulate some happy number-crunching!
>All the following data relates to the ballistics from an M4 Carbine (14.5 inch barrel):
>- bullet weight 62 grains, G7 BC = .154
>- velocity at the muzzle = 2,995 fps; at 300m = 2,096 fps; at 600m = 1,335 fps
>- wind drift at 600m and 5 mph cross-wind: 28.2 inches
>- bullet drop at 600m with 100m zero = 116 inches

>From the same source and from the same barrel length, the same data for the MK262:
>- bullet weight 77 grains, G7 BC = .169
>- velocity at the muzzle = 2,664 fps; at 300m = 1,893 fps; at 600m = 1,247 fps
>- wind drift at 600m with 5mph cross-wind = 30 inches
>- bullet drop at 600m with 100m zero = 145 inches.
