Does it matter? Sure, if the gun and shooter are up to snuff and can truly see the difference. I would say that 99.9% of shooters and firearms are not in that group, I know I am not. Just because a BR shooter does it doesn’t mean it has relevance for Joe 6 packs and his 94 Winny.
In handguns it matters a whole bunch. Small cases like 9mm are very sensitive to case volume- it is a pressure thing as much as an accuracy thing.
I will say this- it is not something I even think about outside of good neck tension for handgun loads.
