Convertible or not?
I also own and enjoy a single 6. If Ruger makes the new single 10 in a dedicated .22 LR version I would purchase that vs. the convertible model.
My only disappointment with my convertible single 6 is it is more accurate with .22 Win mag vs. .22 LR.
The barrel bore is one thousandth larger to accommodate the .22 magnum round.
That larger bore has a negative impact on .22 LR accuracy. I can shoot tighter groups with Win mag vs. .22 LR.
My example is quite accurate with win mag, with .22 LR not so much.
.22 Win mag makes for expensive target practice, I think I can shoot my 9mm reloads cheaper.
