This is the beauty of LRH…we can start talking about something found in a barn and end up discussing the health merits of flatulence and nobody's mad (I hope). Also seem to have got an answer to the original question to boot!
And while this is a great derailment it's not derailed into anything political, religious, for or against Sherman cartridges or hammer bullets, and no one has invoked cold welding, carbon rings, donuts, the Coriolis effect, spin drift, temperature stability, hoarding, the need for ADG, Lapua, or Peterson brass, the definition of "ballistic expert", or opinions about how expensive is too expensive
. That's some kind of record on this site!
Farting is a welcome change of subject derailment
