Chris is correct. I was introduced to this little-publicized fact while making my own 44 Automag cases from .308/7.62 brass...(I had one of the High-Standard 44 Automags w/ both 357 Automag and 44 Automag barrels)...I was getting a lot of case failures while forming, almost all military brass (the others were much-used commercial brass). Also, the military brass had to be neck reamed; the commercial didn't - this was the tipoff. 44 bullets could be seated with no neck reaming in commercial brass cases (after cutting to length).
I would expect the military brass is made with thicker walls intentionally, to lessen the chance of a blowout...while commercially, the manufacturers want to hold costs down as much as possible...
Case wall thickness (*not* neck thickness) only seems to be an issue for those of us concerned with 'cartridge conversion'...
BTW: I am not stating that you
won't have to neck ream .223 commercial...only that you may not need to...
Off -topic = I can recall back when only Berdan primed cases were available for the 7.63 Mauser and 7.65 Luger, there were all kinds of ways to remove the spent primers...some really crude...("fill case with water and use a tight fitting dowel to hydraulically eject the primer")...
Disclaimer: I am not an expert on any of this, these are just my observations from practical experience...
Lessee...What was this thread about?...
