[QUOTE="SidecarFlip, post: 830151, member: 39764"] Sounds to me like your projectile (bullet) is too far out of the case (when loading in the rifle) and it's hitting the lands when you try to close the bolt. Are there rifling marks on the sides of the projectile (look closely at the ogive) and see if it's marked in any way. You need a certain amount of jump from the seated bullet/brass to the lands prior to ignition. Different guns, different jump. My rule of thumb is 10 (thousand's) or more off the lands as a starting point. Try loading one to Sammi specification for COAL and see if that eliminates the issue. [/QUOTE]
