RE: Bullets too long?
That little round thing on the boltis the ejector. If fired cases have a round mark on them that is about the same size as the ejector, it is generally a sign of high pressure. If the mark is made when closing the bolt, before firing, it is usually a sign of too long of a round - either not resized enough, not trimmed enough, or bullet seated too long. .22-250 cases do need to be trimmed. Every shot if the load is hot. And too long of a case can really spike the pressure curve of a load, since the bullet is not being released from the neck smoothly. 1.912 is the maximum overall length for a .22-250 case. Should trim to 1.902". Hope this helps. Roskoe.
