From: Amos Shapira <amoss%BATATA.BITNET@CUNYVM.CUNY.EDU> The data on the new (well, not so new) ammo is as follows: Calibre : 5.45 (obviously) Bullet weight: 53 grain Bullet length: 25mm Round length: 56.5mm Case: steel Muzzle speed: 870m/sec (fps are not used by the enlightened) Max distance to peirce a metal helmet: 400m The bullet is very unstable in flight because of a small air pocket in the tip of the bullet. The instability (tumble) decreases effective penetration range. The shape of the bullet, its low muzzle velocity and its low weight result in effective battlefield range of 300-350m. However, up to the maximum effective range of (say) 400m the bullet is said to be very effective. Amos Shapira, PVT Marc A. Volovic, SGT (res.)
