[QUOTE="Lou270, post: 2907177, member: 5352"] Yep - somewhere in the .5s is about where seems like bullet designers have topped out with what they can get in a 150 lead core that will go in a 1-10. Badlands has a 150 bulldozer with a bc of .710 which is extraordinary but requires a faster twist. You can shoot heavier bullets - 160-180 in 1-10 270 but they cannot be optimized ballistically to stabilize in 1-10. For ex, woodleigh makes a 270 180gr with bc of .5 that will stabilize in 1-10. If maxed out BC with long secant Ogive and boatail it would be above .8 but probably require a 1-7 twist Lou [/QUOTE]
