bore on single ten

[wc beagle]

Is the bore on a single ten cut for 22 LR or is it cut like the 22 convertible?I understand the 22 convertible is cut a little larger for the 22 mag

I'm sure it's cut for the "compromise" bore, like the rest of the .22 Single-Sixes.

They did this on the .22LR-only guns in the recent past, such as the "Star" and "Arrow" marked guns, as well as the single-cylinder Bisley guys.

IIRC, the "compromise" bore has been in use since something like 1959...

WHAT DOES IT MATTER ?? Have you checked the accuracy these guns are delivering in published gun tests of the Single-10 ??
