DD, your suggestion is a good one and I initially wanted to go that way, but was dissuaded by the relative unavailability of Cadet parts. Then the concept of an offset bore occurred to me; been done plenty of times before, it ain't rocket science, but the extraction would work with only one particular case head size. It happened to be the 30-30 size, you'll notice all the ones I mentioned above are that size. I could also have probably used either of the 303 Savage or 30-40 sizes but IMO they are slightly too large for loads above 40K.
Regards, Joe
So the 30-30 extractor has sufficient contact to extract? What did you do about the exposed sides of the rimfire case? Any problems with bulging or rupture of the unsupported sides?
