I did. Beautiful rifle, but for me it ultimately comes down to fit and how a rifle hits for me. I preferred the heavier barrel contour on my 57M classic and how it balanced, and the Coopers stock shape is absolute perfection to me, so eventually the K22 Custom Classic went away.
About 10 years back, a K22 Super America fell victim to that same 57M.
One of my many shortcomings, occasionally I seem to think that I need just one really good of something and the rest is simply inventory so I sell it. An obvious character flaw.
