Your best bet is to get with one of the established gunsmiths and use the reamer they are. They will also either have a recommendation for, or even have their own sizing die made specifically to work with that chamber.
Spot on.
Time for one of my frequent trips down Memory Lane (sorry). When I built my first PPC (in '79, I think) I went with a .264 neck. The Sako brass we were using at the time would just barely allow the use of a fitted neck (which some thought was the best for ultimate precision) which meant turning it to measure ,2635, over the seated bullet. Not all of the cases would clean up (maybe 5% or so). My 264 neck worked fine though and it worked even better when I eschewed the fitted neck concept and decided to size the necks. Nonetheless, when my next batch of brass showed up thinner and maybe half of them wouldn't clean up, I ordered a reamer with a .262 neck, at the request of some customers. For myself, I continued to chamber with the ,264 neck and liked it fine.
When the 6BR was announced, I got a reamer right away. I ordered it with the factory neck of .266. Since the Remington brass was just thinner 308 brass which was formed to the BR, there was plenty of brass to work with and it was the BR which first made people aware of the "dreaded donut".
Now, it might seem strange to people today, but I loaded all of my ammo with standard Bonanza BR dies. My assumption being, when I check runout it was under .001" and often zero, and that was as good as I was likely to get anyway. The rare piece which was over .001 became a fouler. Anyway the first Bonanza dies in 6 PPC sized to just under .262, so they worked great with my .264 reamer. Later dies sized to , 259, or so, and the .262 neck was a better fit.
Now, the 6 BR dies, as initially produced by Bonanza, sized to .262 or so, and this was fine for the factory chamber (at .266) with necks turned to .264, over the bullet, and I was a happy man; until I got some new dies from Bonanza and found that they sized to .258! I called Bonanza, and asked, "what the heck?", or words to that effect. I was told, Fred Sinclair had decided .261 was a better diameter for the 6 BR, so they were making their dies to match up with that diameter. I was pissed! I never bought another set of BR dies from Bonanza, and it was twenty years later that I finally started chambering BR's again ( sometimes, I pout a little)!
Today, I shoot one original .266 BR and one BR Norma at .272. I recall when Jackie told, on BR Central, about trying his no-turn chamber, and I thought, "Well, crap! I've wasted a lot of my time!" I still turn necks, for some rifles, but I think it's pretty clear, if the brass is at all consistent, it's an optional step; not a necessary one. WH
