[QUOTE="azsugarbear, post: 1034820, member: 4809"] Your first link takes me to a page on the GSC website that outlines specs for their 257 gr. bullet. About 2/3 of the way down the spec sheet they provide min required twist rates: 7.3" twist if under 300 yds; 9.0" twist if under 620 yds; and 10" twist for targets beyond 620 yds. This implies that with a 9.3" twist barrel your bullet will stabilize (or be accurate) only after about 700 yds. With their heavier 338 bullet, the recommended twist rate is even tighter to get accuracy performance at shorter ranges. To me, this is a huge shortcoming in a hunting bullet. I would need a barrel with a min. 7" twist to stabilize the bullet at shorter distances - making the barrel of little use for anything other than mono-metal bullets. I will readily admit that I have not studied these bullets in great detail. But again, am I missing something here? Not attacking you, my friend - just trying to understand the advantage of this $2 bullet. The ability to open up at lower velocities would be a major plus, but that remains to be proven. [/QUOTE]
