Back several decades, like 3+ we didn't have the tooling or the lathes we have now. I can't tell you how many Remingtons I built just chasing the threads with a tap to clean them up. Trued the receiver face along with receiver and bolt lugs and they all shot just as good as the ones I build now with trued threads. Whether trued or not the key is loose fitting threads. Loose threads mean square shoulders.
Dave, Thanks for saying that.
