Ripp,

Thank you, That is a nice writeup on the history of the 22/250.

While off the subject, there was a mention of a 22 Newton which I understand is about 1/4" longer than the 22/250 and was intended for 90 gr bullets (0/228" dia.) which with modern powder could be an interesting long range cartridge. I saw that cartridge cases are available at https://www.ammunitionartifacts.com/unitedstatescartridgecases/22-newton
