Thread: 7mmSaum test fire

Interesting results - the CZ 7x64 that I've just traded back to @nor-west gets 2820 fps with 53.4 grains of powder with the Sierra 160gn projectile and the same sort of accuracy (from a 24" barrel it has to be said). It'll run at 2950 fps but that isn't in a node so accuracy suffers a bit at the higher speed . . . .

Yeah, @Tentman the 280/7x64 is superbly efficient. I use 6 more grains of powder to get 3k but do have the advantage of a 22" barrel and a 5lb 10oz rifle. I like light and quick.
