Lake City brass differences??

I have a decently large quantity of Lake city 7.62 brass with many different manufacture years.
Standard and Match.
I've often wondered if the different years of manufacture made any difference in accuracy or reliability.
Is LC just LC or is there some preference?

Try to sort it based on headstamp years and then you can pool the one's together that weigh the same. They should be very close across years as the specs do not change and they are built to a certain specification.

NATO headstamp cases like Lake City and Federal weigh pretty much the same. If you can ever get your hands on some Federal NATO I suggest you do it. That brass always weighs so consistent it boggles the mind. I mean one to three tenths of a grain spread in 100 deprimed cases.

I've won money using LC brass with a 20 year (or more) span. The weight spread from case to case is usually about as big as the spread from year to year, that is, minor. Unless you are shooting in the Olympics, forget about it. Concentrate on B R A S S and let the rifle do the work. You will have your hands full reading the wind and focusing on the front sight. dave

Lake city brass differences

I have a lot of 69 and 71 LC brass and smaller amounts of other years.

I assume that if I weigh the cases no matter what the year
that would be good enough.

I also have a good quantity of Lake City Match and LR
brass.
I know not to reload the ones with the serrations near the base but is there a difference between the Match and the LR?

yep. sort out by:
A) LC NM (awful hard to get these days)

B) LC
(1) year-by-year

I'll bet you a beer you won't find minimal differences year to year in case weight or volume.

P.S.
Store the LC NM as your "stash," while you re-load and shoot up the LC.

I have both, and have been buying and selling LC M118LR brass for 2 years now. I have found the M118LR brass to be slightly more consistent weight-wise than M118 Match brass.

I've shot about 2500 LC 89 NM and 2000 LC 90 through my Supermatch. There's no difference that I can detect on a target.
