[QUOTE="Tiny Tim, post: 2023966, member: 87887"] No stupid questions exist. 1 in 7 means 1 complete revolution of the bullet in 7 inches of barrel. 1 in 8 means 1 complete revolution in 8 inches. Therefore, a 7 twist is faster and will impart more spin or "stability' to the bullet. This not only affects accuracy but can also affect terminal performance. As previously pointed out, a SG of 1.4-1.9 seems to strike the best balance. [/QUOTE]
