Mmm throw them away?

Need to understand how in the OP's case the donuts were formed although I couldn’t actually see where he had a problem with donuts? Yet.

With my 284 mine formed in part from neck turning and in part from brass flow over several firings. Some cartridges are more prone to brass flow.

If for example, shooting boatail projectiles and the projectile boatail to bearing surface junction doesn't seat into the donut there isn't a problem. Or for that matter flat base projectiles that don't seat down far enough down the neck to contact the donut.

Otherwise I cut the donut out using a K&M carbide mandrel with the cutter on its tip.
