Re: Brass Preparation And Management By John W. Lewis
Personally I thought you did an excellent job explaining in detail the why's, the how's of of turning the necks of brass cases. As a machinist, toolmaker, tool & cutter grinder in the machine shop trade. I also worked for 25 of my 46 years in a specialty shop as a working supervisor (I never stopped cutting metal for 46 years). I've cut to tolerances of plus or minus .00005" at times. that's 1/2 of 1/10,000". I've learned that when you're working to extreme accuracy such as needed in long range bench rest shooting, you never know for sure, how something seemingly insignificant can affect the end result.
Because of this, you can perfect factory brass beyond what the factory can do with a cost far less that what most people could afford, if the factory produced brass to the same consistency. With factory brass, you never know when you might have a case or two beyond factory tolerances. Even meticulous inspection sometimes misses less than perfect manufacturing. Normal inspection might check 1 out of a 100 cases, better inspection might check 1 of 10 cases, but there will always be some that get through without being checked.
Maybe if you're shooting woodchucks, a miss from time to time doesn't mean much. It easy to blame it on something else. But if you're shooting 1000 yard benchrest matches, one bad shot could cost you the match. Shooting woodchucks, you can easily chamber another round, no big deal. But shooting a match, you don't get to say, "Gimme another shot." If you have a flyer for any reason, you're stuck with it.
What you wrote was excellent.
