Small add to the comments -
Accuracy wise - it’s the Brass spec to Chamber spec’s that make it accurate - meaning it’s NOT JUST the chamber spec.
Some of the best gunsmiths have known this for years and buy custom chamber reamers to keep these types of tolerances between the brass and the chamber.. couple it with precision chambering and you get a tack driver as long as the barrel is good..
AND it's the throat diameter spec to bullet diameter relationship.
