Already have my bbl and action ready. I have a 223 bolt waiting to be cut. What are the dimensions needed to complete this conversion? I know the case is .447 so I was gonna open the face up to .454. I'm not sure whether or not I need to deepen the face as well, I'm thinkin no. Does the extractor need to be thinned a bit on the inside wall, to makeup for the new radius?

Please don't suggest I go talk to Fred at SSS. I have been calling and leaving messages for months now about this project. If they're too busy to get back to me then they don't need my small donation.
