[QUOTE="Bullet bumper, post: 953506, member: 17844"] It could also be " In bore yaw " no that's not a foreign language or a southern accent . It means when a bullet does not go down the bore perfectly in centre so when it exits it can wobble or gyrate to some degree , but as the range increases the spin rate tends to settle it down . Dynamic Stability . The ability of a projectile to dampen its initial wobble and thereafter fly straight and true to the target. Check your twist rate is good enough for the bullet length , check your load is hot enough to get the bullet expanded to the bore , check your barrel is not over fouled with copper . Check that the bullet is concentrically seated . Try moving it closer to the lands . If the barrel is worn then go to a flat based bullet . [/QUOTE]
