[QUOTE="Mikecr, post: 667203, member: 1521"] More like 7 seasons of LOST.. I didn't see him actually finish with any notions beyond the well established and obvious. As far as I know(and would have guessed), pretty much none of it applied to jacketed bullets and centerfire cartridges/barrels, as well debated at BR Central. Slugging is to find TIGHTEST spots. It's been known since before any of us that the muzzle needs to be tightest, and either slugging or air gauging confirms this. Tell me, what 'spot' would be chosen along 3/4 the length of a parallel fluted barrel, our barrels, to determine through measure of slug -an OPENING of bores'? It's also well known that re-contouring affects bores with inherent stress. But this is way beyond fluting. I doubt "quite a few BR shooter put his theories to the test and found the variances" from FLUTING. That would mean they air gauged(rather than slugged) before and after fluting, and found issues as a direct result. Do you know of an instance where this testing occurred? Another reason for doubt is I have never seen fluting taken through the muzzle. It's typically stopped a few inches from the muzzle, and this would leave the muzzle tight anyway. Known to kill accuracy is closing & reopening of a bore(opening last). Unless fluting is perpendicular to the bore, it could only 'possibly'(if extreme) cause this with hammer forged barrels. With all others, and parallel, it would only cause opening & re-closing, at worst, which has been good for accuracy if nothing else. Now there is potential there with contouring(reverse taper). Not much if any with mere fluting. [/QUOTE]
