What's us with quality control of Lake City 223 brass/ trimming a five gallon bucket of processed brass/ notice when trimming at 1.75 that some was short at 1.731 and some neededcalot of trimming/ took a hand full and measured them/ 1.731 to a maximum of 1.792/ to me that's a big difference/ anyone else notice this

Does a machine gun or an M4 really give a damn?

Unless the the brass derives from a single chamber I'd draw no conclusion from that length variation.

Even if it does I have never seen each and every piece of brass from Lapua, Nosler, Norma, Federal, Remington or Winchester blow out to the exact same length on first firing. This is true, but a matter of degree. OP describes a variance of 61 thou. I'll occasionally see as much as 6 thou difference in stretch in a batch of 7.62 or even .375s - one headstamp, fired in one chamber. Multiple brands would increase that variance, sure. Which brings up another issue. Metal to be trimmed comes from somewhere. I sometimes use bulk 7.62 brass. But step one is to run every piece into a Wilson case gauge. Can do this while watching a movie. By feel. Cases noticeably stretched get culled. Right then and there. Cuz I don't need to waste time, sizing die life, and lube to discover cases that a) might still be hard to chamber, b) will require more trimming than most of the rest and, c) are destined for a partial case separation. Those culled cases were overstretched on first firing. M240 chamber? Whatever. I don't need the aggravation. Just part of the economics of bulk brass. I'd take the same approach with 5.56. If I weren't so lazy.......I just shoot factory in 5.56.

I have buckets full of military brass, 223, 308, & 30-06. Military brass is a lot of work. I use the 30-06 military brass only for cast loads anymore. I now have enough ‘factory’ brass for the 308 & 30-06 that I don’t use the military brass for hunting anyway. But 223 - I’ll load up more than a thousand 223 loads for a PD shoot some times.
Military brass is cheap. But like I said a lot of work. One thing I do with any new to me brass is to trim it to length. I’ve also been known to measure neck thickness to be sure one side isn’t thicker than the other, measure the flash hole to be sure it’s centered, and weighed the brass throwing away brass that varies to much in any area. I’m glad I did that when I was younger. I don’t think I’d do that again.
As I recall military brass isn’t pristine, even the ‘match’ military. But it is cheaper than Nosler brass.

Small base dies from RCBS in 308, 06 and 223, seems to bump things back into more consistency, when I first size the brass.... Most of what I have for brass is just range pick up brass, and there is always tons of it laying on the ground at our local range... one thing ya gotta love about those Californians.. use our range, and just leave their brass laying all over the ground.... as I've heard all too many times from them...

Since Winchester got the contract I wonder if the quality is still held to the same guidelines.

I like Lake City brass and I am willing to work it until it fits my needs. I have noticed that the lengths vary, sometimes by a large amount just like Stevered describes. I do sort mine by length. The short stuff goes into my bolt actions (1.754 and shorter) and the longer stuff I use for semi automatics. The longest I trim is to 1.765. But most of it falls into the 17.55 and 1.760 range. Yes, this means measuring it with a set of calipers and bagging the different lengths and trimming it to the length I want. But, it's good brass and it's worth the extra work.

I must be living right... I trim Lake City Brass and other brands, after I've had 10 to 15 reloads on them. Back off the gas pedal on the powder charges just a hair or so.
50 plus reloads out of a batch of 223 and a lot of other cartridges I shoot is nothing out of the ordinary. a little prudence on the reload bench, and annealing often works wonders...
between that and range pick up brass, I really don't have a big investment in the brass dept.
Ya learn some secrets to take care of it, it'll last a long long time.
Yesterday evening and later this morning, I'll be over at the range, ringing steel at 300 and 400 yds, with a 6 x 45, and an 80 gr SP, pushed along by Small Pistol Winchester Primers and 10 grains of Unique. Just practice, but that kind of service, that brass will last for a 100 plus firings...
I use to learn everything the hard way, just like Hanco above. But I learned to pay attention and apply what I learned on top of that...hence how I've learned to stretch out components life span.

All this brass was fired out of the same gun/ not a machine gun or an M4/ all factory ammo/ that's why I say the Lake City must have QC issues/ brass length from 1.731 to 1.792 is a big difference for once fired brass.

I run all of mine through small base dies, ream out the primer crimp, trim to trim length because I’m loading for two Rock River AR’s.
What difference does the length make when you get it make as long as it still holds the bullets? If it’s a touch short, does it hurt anything? I’ve used a ton, because my boys best friend brings us Lake City when he comes home. I’ve never seen any shorter than trim length.
