[QUOTE="Hand Skills, post: 1501242, member: 103303"] But is there such a thing as too much SG? Take berger's default example in the twist calculator [USER=102831]@SapperRIP[/USER] linked; At sea level the SG is 2.42 At 30,000ft, the SG is 8.14 Same bullet, same gun. The only variable that changed was air density. Of course, no one is going to use a .308 at 30,000ft, but there are guns that operate up there... Is there such thing as too much twist? Yes, we all seem to agree on that. I'm not sure why we are so divided on SG however. Perhaps there is misunderstanding in the question or the terms. [/QUOTE]
