[QUOTE="tacomHQ, post: 2889363, member: 67159"] The best School there is. The guy who pushes a button and watches a multi axis machine center... is a bit limited. His input is limited. You obviously are not limited. Even if you don't have pages of measurements, measured trends, failure modes will start to paint a picture (ugly) but will help lead to a clear measurable picture. What I note is your shooters seem to be pretty successful... No big issues. Your continued success while "maybe" not a measured statistic is certainly a trend measurable if it were plotted. Hard to ignore that trend. We were recently told our barrels don't work by a very respected facility. They have never shot one or ever will. They note that barrel harmonics don't effect accuracy. That our successful shooters ( "I am sure they are good shooters but..") don't have data to counter theirs. Where the term "anecdotal" arose. Harmonics is "old school thinking, vibration of a barrel won't have 1fps effect on speed (variable geometry cutters ?? I guess are a fluke too), group size, group placement" ... but I have faith in our shooters/clients and the anecdotal evidence is very very high. I at this moment don't care what the experts are saying I am watching the trends... It seems the implication is that other than twist rate, assuming good inner dimensions, a barrel has nothing to do with accuracy. (A bit of stirring the pot- ) If I may ask- grooving of the bullet - material has a high impact on the consistency of the groove event and its repeatability. You must work to a specific source and material grade. Toot your horn. Of course you might come back and say "material" has nothing to do with bullet performance... [/QUOTE]
