[QUOTE="Roeder, post: 1645857, member: 87340"] What you have in mind [I][B]might[/B][/I] work. Several of the custom action makers offer a "universal bolt face" which is large enough for .308 diameter case heads but will also work with PPC cases. That is nominally a .033 difference. Not everyone has been happy with this option. They are shipped with an extractor with a little extra reach. I have ended up trimming them a tiny bit to get them to snap over the larger case easily, but then a new extractor is needed to extract PPC cases. Other factors such as the depth of the bolt recess and the position of the ejector and extractor could keep this from working out. If you could make up a Dummy barrel stub with the correct chamber diameter, you could test it out before you actually chamber a barrel. You may need to lengthen the extractor by tig welding a little extra material and re-cutting. The extractor should allow the case to move over against the opposite side of the bolt recess and still have a little tension. Jobs like this take some tinkering and gunsmiths often avoid this sort of thing because it is hard to predict how much time it will take. [/QUOTE]
