Fudd, I sympathize with you, not being a rifle guy. I found a load that would shoot ragged one hole groups at 50 yards with my 1922. It is serial number 251, so I guess mine is what, 101 years old? I don't know much about the serial number versus date of manufacture of these great guns, but considering its place of origin at Colonel Whelen's shop, I have only questions, no answers.
