200 yds... not worth the trouble. At that range you won't see enough improvement to make any difference.
It's Lake City.You also did not identify if you are asking about 223 or 5.56 brass.
LC brass does not vary that much year to year, it is all very specific and controlled
That all said I always separate by year and I almost exclusively use Lake City brass and both 223 and 308 . For 308 Lake city brass it has variances as much as 2 grains of case volume measured by water fill from year to year . I have found Lake city 14 to be my worst lot of brass that I use in 308 .
Out of the billions of rounds produces, you think a year stamp is gonna matter?
Yes.
First you said "Maybe, Maybe not"?
Show us the difference
Better get a $600 electronic scale to measure 1/2 of a stick of powder as well

If the year date is a concern, perhaps one should find the Month it is was produced. Certainly with all these variances, then is brass made in January so much different than that made in December.?? Who Knows what machine it came off of?
Then narrow it down by week and day.
Based on this chart (it's old) then Lapua or Hornady would be the best choice.

As I posted earlier it is all much to do about nothing! Perhaps the top rated BR people have such concerns but for 99.9% of the other shooters, no.
I would have to say to the OP, assuming you don't get the results you are looking for, you would have to invest in a small lot of brand new, premium brass... and work up from there. LC brass, no matter how good it's supposed to be (and in my experience, it's not...) is still mass produced, and probably more so than any other brass headstamp available here in the US.
Maybe or maybe not. Is not an answer Well then what is the purpose?
Perhaps the top rated BR people have such concerns
Absolutely.7.62 and 5.56 LC brass are two entirely different subjects.
do you sort LC brass by date?
The OP may need to explain how the powder in the case knows what year the case was manufactured.
Is the year a proxy for case volume? As far as I know, powder volume is the only thing the powder load knows.
I suggest OP measure case volume by year to validate their implied assumption.
