[QUOTE="Boss Hoss, post: 258965, member: 5060"] Speedy Gonzales did the testing on 6ppc brass that he fire-formed fro 220 Russian Lapua. That should answer most of your questions. The total number of pieces of brass tested I do not know but will find out if you need to know. The reamer he uses are to his spec for his competition rifles. One does not usually set world records get into both major shooting disciplines HOF's by not knowing what one is doing (he builds his own rifles). How many matches, championships, or hall of fames are you a member of? Skins on the wall go a long way to validate ---- talk is just that talk. The attached link is just for the picture and introduction not the barrel cleaning routine [url=http://www.rifle-accuracy-reports.com/barrel-break-in.html]Barrel Break-in[/url] The short answer is and this a direct quote "sorting brass is a complete waste of time but some people do it to make themselves feel better and if that works for their program then fine" ----- "my testing showed that there was no advantage because just because there is a weight difference that may or may not have a bearing on volume differences" ----- “you may be doing more harm than good by discarding a case that may be heavier because the interior volume may be the same” In his testing Speedy also checked internal volumes on the test cases to determine that the weight differences were indeed not having a cause and effect relationship on the volumetric capacity. Volumetric differences of the internal part of the case are not systemic to the weight difference of the case alone. Speedy also for example has the most intricate procedure for turning brass necks that I have ever seen or heard of. Just for example, he grinds the mandrel (specific type of tool steel) to the exact diameter that is required based on the measurements taken from the actual neck size of the brass being turned. Then uses a lube he has concocted himself and then has the lathe set at the exact speed that will give the best most consistent cut while not building up heat that will cause variances in the process. This is just one of the tricks he has shown me but it suffices to say that if something will make a difference in the accuracy of the bullet going down the tube he has either tried it or does it. I have never been able to think of anything that he had not already done years ago--not to be say that there is not anything that is not already known but everything that I have read on these types of forums was tried a long time ago.
