I was reading through some of these long-dead and seemingly unresolved threads to see what all I've been missing, and figured I'd reply to this one just for kicks. I believe what CZ was getting at with the 1000 yards for the .300 mag vs the 800 yards with the .308 has more to do with the cartridge than the rifle. The .308 will be just as accurate as the .300 mag, but it will not have as much energy. Hence, it will not be as effective at that range. Also, ballistically speaking, the .300 mag would have a definate advantage at 1000 yards because of the bullet drop.
As far as the term "sniper rifle" goes, I think CZ should have given it a more suitable title, as most people who buy the rifle will certainly not be using it for that purpose. The marketing department must have thought long and hard about that one. Your average deer rifle would fit the bill of "sniper rifle" just fine. I think "precision" rifle would be a more accurate (pardon the pun) name for the rifle.
