Larry, I understand how you could shade the argument toward the view that really getting down and dirty with the mils would ALSO ring a bell for these guys but you do have to remember that many of us don't spend weeks and years with a caliper or mic in our pocket. There are very savvy people on this board who are "innumerate" when it comes to getting the decimal point in the right pew. So, yes, I agree with you and Bill that it is better to know the diameter of the bore and the minimum diameter of the choke and I agree with David that patterning with your load of choice tells the final tale and I agree with Bill that a big backbore and the original choking could produce, in Bill's case in hand, a constriction of say .11". I agree to agree and I agree to not be quite so vernacular and shorthand in future. I understand that I'm being held to a high standard of commo and I take that as a sign that there's some hope for me.
