Graham, you had seven hours to answer him before I did. I just threw a fairly reasonable answer out there knowing that someone would be around soon to correct ("correct" is the wrong word here. Should have said "confirm or refute".) me. Who could have guessed it'd be you? (another lapse of judgement, never attempt humor when dealing with a lawyer.)
I didn't "know" my answer to be incorrect, still don't. I would imagine one could find Winchester Model 70s in a variety of twist rates to meet a variety of uses. But I do apologize for what you feel is criticism, I shouldn't have risked injuring your sensitive soul.
