[QUOTE="entoptics, post: 1644589, member: 104268"] I would disagree with the idea that the Remington brass is a lost cause. I've made plenty of loads that were better than the guns or shooters they were meant for, using scrounged brass of various kinds. That being said, if you have a serious gun and/or are a superb shooter, then maybe you will see a difference. IMO, there is not much point worrying about concentricity of the brass until you've fired it once, let alone before even sizing it. Even new brass that is WAY out of spec (>0.005 runout or so), might be just peachy after you fire it. If it were me, I'd weight sort the brass, select a few pieces with similar weight, and perform the following steps. Load those up, and do a direct comparison against the Berger factory ammo. If you get equivalent results, or better, then you know you can do fine with what you have. 1) Ream all the flash holes for "dangling chad" and uniformity. 2) Turn all the necks to the same thickness, with a tolerance of about ±0.0005. Unless the brass is excessively thick (>0.015"), leave as much as possible. If a piece of brass is so bad that you can't maintain a neck thickness of >0.0125" then it should be culled. As mentioned, you don't need to turn them down any more than necessary. When I'm done turning a new batch, VERY few, if any, of the necks will have been completely touched by the cutter. Just take off the high spots, so to speak. You may need to turn a few to figure out what the ideal setting is. Set it thick at first, turn a few, see how much is remaining, lower the cutter a smidge, rinse, and repeat till you find a happy medium. 3) Run through a bushing sizer. You may have to guess the right size bushing at first, or better yet, measure a fired piece of brass with uniform neck walls, then calculate the right bushing based on that. 4) Load up 20-30 of the above, and see if they give you consistent results compared to the Berger ammo. If so, do the whole batch, and enjoy. If not, toss the brass and buy a 6.5 Creedmoor, as I've read it's a 1 mile lightning bolt with cheap factory ammo...;) [/QUOTE]
