Does cartridge/chamber orientation matter?

Are there circumstances where an increase in accuracy can be recognized if your reloaded rounds are consistently oriented wrt your chamber each time you fire them?

i.e. mark the case and always have the mark facing up when you chamber the round
 
There are some things that you can do to make good ammo and plenty of things you can do to make great ammo. I will bet that 99 % of shooters would not be able to produce better groups by cartridge/chamber orientation with bullet run out of .002" or less.
 
While in theory, such actions can work; only the most careful benchresters would ever know the difference. Hunting uses make such practices unworkable and unnecessary.
 
I have had two Ruger #1s that had wonky breech blocks or seats to the extent that when standing a fired case on a flat surface, the case had a visible lean to it.

This was kind of an extreme case, but aligning the cartridge (which of course was easily done in a #1) made for much smaller groups.
 
Some of the long range black powder crowd swear by this sort of thing.

They notch their bullet mold and the rim of the brass and always align everything in the chamber the same.

Yes, my old Winchester 1885 Hi-Wall .38-55, which is in another CGNer cabinet I used, only 1 case, seated the bullet same oriientation and dept in lands, primed, loaded powder case, pleget of kapok, inserted case to read Dominion and let loose. This rifle is still being used in the same way
It is very happy with its new owner as I am too, we are both happy:):)
