30Cal, most folks shooting the original 155 do so from 30 to 31-inch barreled Palma rifles. Their nominal muzzle velocity is 3000 to 3100 fps. Under these conditions they buck the wind better from them better than the 168's do from more conventional barrel lengths. But the 168 has less drag that the old 155.

Sierra's newest 155 has less drag than the original; better than the 168.
