When i was 8 years old,every boy knew what size drillbit would do a 22 chamber......Ive forgotten,but a quick reference to the net would do the trick......anyhoo,if a boy with nothing but a few rocks for tools could do one 70 years ago,see no reason someone with a lathe and all mod cons,not to mention the net for info,was unable to do .......I might add ,in those day there were no gun collections in my district.....a rusty 22 was the farm gun ,and a packet of ammo that lasted all year was what could be afforded.....Really rich people had a 32-20 ,either a Savage or a Winny.....but never fired expensive ammo willy nilly...........................PS find out about using a D bit as a chamber reamer for one offs.
