[QUOTE="Kevin Thomas, post: 473636, member: 15748"] No, it's not normal. Something's wrong there, and my guess would be too much neck tension. WWithout knowing what you're sizing the necks down to, I can't say for sure, but it sounds like it's just taking too much pressure to force the bullet into the case, leaving a ring on the ogive as it (the bullet) swages the neck open. May also related to the shape of your seating plug, and its not being compatible with the profile of the bullet you're using. Common for several manufacturer's dies to leave these marks, and most offer the service of profiling the seater plug to the bullet you're using, or alternate seating plugs already so profiled. You need to take a look at the whole system, step by step, and see just when the marks are becoming a problem. If there's any way you can reduce the neck tension, I'd take a look at doing so, and see if that helps. A mandrel die like those from Sinclair should do the trick. [/QUOTE]
