Have to admit, blunt and to the point, EH!!!!
I have a machine that Gary Hayes built for me with a 3 jaw chuck that I have a Lyman shell holder installed. I fire form then run the brass through 2 cutters on the machine and away I go. The brass is ready!! Me thinks, and always have, that too many people, spend too much time, at the bench, building that perfect round only to miss a 1/2 inch condition. Another pet peeve of mine, so many shooters ban powder measures and the like, try to create the perfect round, to get their SD to 15 or under and I do that all of the time with my obvious mistakes and get SD of 5 or under. In fact I have an Ohler 35 that I have not taken out of the case for 5 years or so. You hear people say that, well I use a .058 button and I went to a .057 button and my groups went from .500 to a .100 BULLS__T, do you really think that 65000 lbs per square of pressure gives a crap on a piece of brass, if you use a .057 button instead of .058? And if it made that much of a difference, you had another problem. Do you really believe that your neck is at 8.2 as compared to 8.1 that at 65000 lbs per square inch of pressure, upon firing that it is going to make a difference. Just keep your brass about, on a .262 chamber, or any size, at about 2 to 3 thou under, Example I have all ,262 chambers, I keep my brass at about .260 MAX. If it measures .2595 or .2605 with the loaded round, it will still be in the same hole and a SD of 5. I guess what I am trying to say is the most often mistakes are in the rifle or scope. Can never understand how a person will build the perfect rifle, unlimited dollars, the perfect round, unlimited dollars, and top it off with a cheap scope.
God I hate Sunday mornings in the Winter.
