[QUOTE="J E Custom, post: 621959, member: 2736"] If a chamber has to much head space it can help. The problem is that it leaves part of the case head unsupported and if shooting hot loads can damage the case head. Most bench rest shooters neck size only, so it does not come into play. I have made a few of these modifications when nessary (Due to excessive head space) by installing a steel pin the same size as the ejector and a little longer than the bolt face to the bottom of the hole dimension, cross drilling the pin using the ejector role pin hole as a guide,Pinning it in place and then facing it off flush with the bolt face. This way it can be removed later if you want to, and it supports and leaves no marks on the case head when firing hot loads and does not require re head spacing after removal Note: fire forming and minimal sizing will also prevent this condition. On single shot rifles it is OK to do this Unless you neck size only, then it is not nessary. J E CUSTOM [/QUOTE]
