[QUOTE="J E Custom, post: 1604655, member: 2736"] The SMK may be touching the lands Because of the Tangent ojive loaded to the same COAL. Sounds like the other bullets you used are all secant ojive bullets that will have freebore loaded to the same COAL. This could also prevent the bolt from closing all the way into battery without hitting the forward assist which "Could seat the bullet a little deeper and drive it well into the lands. Pressure normally goes up and velocity normally drops with these conditions. I would check the amount of freebore with these bullets at Mag length. Just a possibility J E CUSTOM [/QUOTE]
