We could get into the details of inside vs outside turning or reaming, but for a hunting rifle, they are virtually the same, accuracy wise.
; With an average of .006" to .008" expansion in the average hunting rifle chamber, a neck that's out of round .002" will make virtually no difference in accuracy.
; In the distant past, I always inside neck reamed and yet even in the 70's, my rifles all shot 1/2" or better which was deemed to be outrageous consistant accuracy for my 'sloppy' Mauser actions.
: I didn't start outside neck turning until I got into the centrefire .17 wildcats on gophers at long range. There, with properly fitted necks and/or much tighter chamber tolerances, outside neck turning became necessary. "0" runnout was the goal and often attainable, but for hunting rifles needed to shoot MOA, inside reaming works fine. Some of them, like the RCB inside reaming system of the 80's(maybe 70's) where the case is held in a die, the inside reaming is as accurate as outside turning. I had a gunsmith make me up a similar system for my .22 BR stuff back in the early 80's and it left case walls perfectly even, using a #1 drill in a guiding die body after partical neck sizing.
: The Forester reamers worked for me, for years.
