Hey DevilDog, velocity isn't everything. The SS109 is too stable, and has an uncanny tendency to fly right through the target. Now, back in 'Nam, before the A1 was introduced, the 1:12 rifling made for an unstable projectile that would yaw on impact. Wen they put the 1:7 on it to accommodate the SS109 round, that was all fucked up. The round now has far less violent damage. Personally, I'd rather the 5.45mm "poison bullet".
