Thank you for your kind words. I'll certainly keep up the program - Mikey's persistent, if not bright. I can't promise a weekly installment, as there will have to be a pause of as-yet undetermined length while I arrange a functional standing rest.
Thusfar, however, I humbly suggest that my researches have already produced at least one nugget of real gold, which may be universally applicable to similar rifles, and which I propose to call (dare I say it? Oh, hell, why not?!) - Mike's Rule of Thumb! :-)
