The only round I know of that can even come close to that is the 7.82 Lazzeroni Warbird, I guess that could be called a semi-factory round. Another posibility is a sabotted 50bmg, and the 50 is a factory cartridge... heh.

Thanks for the info guys I appreciate it.Dan you said about saboting the 50 BMG but is there anybody who actually went ahead and necked it down to 30 caliber.

Akuma - I'll second 338Lapua and say that I have attained 3500 fps with a 180 Nosler BT in my 338 Ultra. I don't think that bullet would hold up well at close range on a large animal like an elk. FYI - Those 180's are very accurate even at that velocity.

The velocities obtained with a 180grn bullet from a 50BMG can surpass 5000fps, the reason why this is not done it that the barrel would be burned out in a matter of minutes. The sabots use a plastic shell, therefore there is not nearly the amount of metal on metal abbrasion.

Thanks DanD for the Info,so you say there is not a barrel designed yet to withstand that kind of friction.Too bad, it would be intresting to shoot a gun that could launch a bullet that fast!!
Well lets see, according to balistics a 180grn Sierra MatchKing traveling at 3000fps with a 500 yard zero will hit at -182.94 inches below aim at 1000 yards at a velocity of 1457fps. On the other hand at 5000fps, it would be -73.16 and a velocity of 2429fps. In other words at 1000 yards it would have the velocity of a 308 Winchester.

I recall somebody getting frantic velocities out of a .416 (Rigby? it was pre-Weatherby) with a very light bullet. Don't know why you'd do it, but shooting doesn't have to be about practicality....sounds like good fun with small furry mammals?

A few years ago I saw a .338 50BMG wildcat in a gunshop in Craig, Colorado. It clocked a 250 grain bullet at around that speed. Frankly, I'm not that masochistic. I'll stick with my 270 Winchester, and pick up my 300 Winchester when I feel really mean.

You are speaking of the 338/50 Talbot, the guy who gave us the Talbot QD scope rings. Velocity for the 338/50 is listed as 3700fps with a 250grn bullet. Again barrel life would be quite limited and practical applications non-existent.
