This was out in 2002 and recalled...I wonder what's new, I searched for trajectories but couldnt find any info.
A new hyper velocity .22 LR load has been added to the Winchester lineup. The Xpediter, part of the Supreme line, is Winchester’s fastest .22 Long Rifle varmint and small game round. The copper plated 32-grain lead hollow point bullet achieves a muzzle velocity of 1,640 feet per second. The Xpediter is flat shooting with explosive upset. The deep hollow point allows for maximum terminal effect
