I have a 22-250 with the barrel more or less on its last legs, so I consider buying a fast twist 22-250 barrel.

It has a detrimental effect on barrel life, but is a very competent long range cartridge.
If memory serves me right, Berger makes a crazy 90gr 0.224 bullet that can be pushed out of an appropriately long fast twist 22-250 barrel at around 3000gr fps.
I think it drops about 7 - 7.5mrad at 1000 yards with 10mph drift of right around 2 mrad.
I think barrel life will not be great and the twist will have to be 1 in 7", but it is supersonic out to about 1400 yards if you are not at sea level.
