[QUOTE="Barrelnut, post: 1310471, member: 74902"] Europeans are not particularly into long range shooting. The American West has been long range shooting for years. The 10 twist is needed to stabilize heavy for caliber bullets, which is about anything over 180 Gr. In Europe they shoot a lot of 160 Gr. type stuff. And are more concerned with a flat trajectory. [I]The 11 twist stabilizes the 160 ~ 180 gr. very well. AND gives them a little more speed because of 11 twist doesn't cause a much resistance in the barrel. This gives them a flatter trajectory. But it is not much, maybe about 40 FPS if that.[/I] [/QUOTE]
