Some years ago, an interesting test comparing Sierra's 30 caliber 190 HPMK against Berger's 185 VLD shooting at 1000 yard target. A chronograph was set up 15 feet from the muzzle of a match rifle and alternate loads of each was fired. 10 feet in front of the 1000 yard target was another chronograph.
Both bullets left the muzzle at about 2570 fps. Their downrange velocity was compared to the velocity at the firing line. At the target, the Berger lost about 50 fps more than the Sierra did.
Go figure that out.
