Thats true from the stand point of theres many gunsmiths out there and not all of them are cutting tight chambers. With a JGS reamer, I prefer to work off of the print. Especially in a bigger case like a 338 Lapua or 300 Norma where it may take 5+ firings to get the .2" line up to chamber size. If a guy has a fat chamber and you worked from the print, then you would just end up sizing the brass a little extra. Much better than not enough. Another issue is that not all cases work with the same numbers. The bigger and tougher the case, the smaller the sizing die needs to be compared to the chamber. .003" under is not gonna work on everything.
