Will also comment that velocity varies with barrel length, though again sometimes not as much as many assume. My CZZ's barrel is 60cm (23.6") long, but for a while I also had a CZ 550 Stutzen (which Americans would call a Mannlicher) in 9.3x62 with a 20.5" barrel. With most load it "lost" 24 to 88 fps compared to the 23.6" barrel on the 550 rifle, when shot on the same day using the same chronograph. But it actually gained 38 fps with one load.
Bullets also make a difference. I first tried Barnes X-Bullets in the CZ 550 rifle in 2004, using the 286-grain X-Bullet, before the 286 TSX appeared. It only took 64 grains of Big Game to get approximately the same velocity as with 66 grains using 286 Partitions, in the mid-2400s.
