Viking- the twist is usually not the most important factor for long range. . what rifle/barrel are you shooting? I beat factory rifles Easily with my hart barrel rem 700 .243- 12 twist shooting 87 and 88 grain bullets at 1000,600 and 500 yards. i never been beaten by a factory rifle in competition. I shot a coyote 496 yards with a 70 grain bullet with it. currently I have 4 sako and 2 remington .243s. plus I load for two buddies also. it is a great round.
Hmmm, and I've beaten several custom barrels in competition with a factory Rem .243 barrel shooting the 105 Horn HPBT. Anecdotes like that really don't prove much. The fact remains that a fast twist and sleek bullet gives the shooter a big advantage when shooting at LR, particularly if there's any wind.
