.223 Remington case length; brass is too short!

lostbit.223 Remington case length; brass is too short!
I am looking for information regarding the case length of the Remington .223 case. All the manuals I looked in show the max length to be 1.760 and the trim to length is 1.750. Sp does anyone know why so much new brass is only 1.743 yes this will work but
not accurately. I have Hornady, Remington, and Nosler brass and many once fired brass. All to short.
I contacted Lapua, they state that their brass is
1.760. Anyone know why I am finding this too short issue?
Thanks

PeterYou may want to post this on the Rifles: Small Calibers forum. however to answer your question I do not believe your accuracy problems are due to brass that is too short (per spec) but rather inconsistent case length. I do not know what rifle you are shooting, but with my BR 222Rem I most certainly trim to a specific case length. I have a Savage 110FP that routinely shoots 1/2 inch at 100 yards with match bullets and trimmed cases. So, uniformity is the key, not a specific case length IMHO.

BoomRMThe last few bags of new (junk) Remington brass I bought were all over the place, and well below minimum trim length. I sorted to find the shortest one, which was 1.743" and trimmed all to match. No issues with accuracy. The Norma I've purchased has always been very consistent at 1.750"+/- a thousandth, and I've never had to do any initial prep - just load & go.....
My .25-06 shoots 1/4" all day long.....

wasbeemanWhen I get a new sack of brass, I check a couple to see that they are below max and then load 'em up and shoot 'em. THEN I find the shortest one and trim them all to that length. (no Virginia, I do not trim them before fire forming.) If that length is shorter than the SUGGESTED min, I don't care. In reloading for accuracy, uniformity is more important than trying to match book specs.

I personally think this is good advice. In the long run the 1.743" is a bonus .

ramrod340I've always started at my shortest case. Sometimes a touch shorter. Then trim everything to match.
Not sure if you can see the effect of slightly different case lengths in a hunting rifle. Then again don't recall actually testing it either.
As usual just my $.02

Foxhunter223Wasbeeman I don't know about anybody else but for me every time I use my Sako 17 Rem I lose 10% of the brass to cracks in the neck or shoulder. This from brand new brass to when I toss the residual away.

BoomRMOkay, maybe "junk" was too harsh. How about bashed in case mouths, differing lengths, off-center flash holes, brittleness, and varying primer pocket depths. As I'm not shooting Benchrest, once I have them prepped to my satisfaction, they are accurate enough for me. Even better, I don't screw around looking for the empties in the dirt like I do with my Norma brass.....

Yep buying bulk Rem brass I feel I need to do a full prep, FL resize, trim etc. I buy Norma and Nosler I load and shoot. Yes Rem is cheaper. I do assign a value to my time. Many don't.

Your rifle might have an over size chamber.

Brand new Remington 375 H&H brass, a couple of years ago.

Foxhunter, does this happen with other brass as well as Remington brass?
If so, Saeed is right on the money, even if other brass does not crack
at the shoulder. However, I've found some Remmy brass to be "brittle" as
well, right out of the package. Because of rough handling during
packaging/shipping, I have a habit of neck sizing all new brass (I know,
that's a bit redundant with quality Norma or Lapua brass). This brings up
the question, "Does Remington anneal their new brass?" Several times, I
used to have problems with neck splitting with new Remmy brass during that
first sizing! When I run into this problem with any run of new brass,
the stuff gets annealed before proceeding further.
Back to the OP, just measure to the shortest case, then trim the rest to
that length. This evens out neck tension which, as indicated above, is
much more important to accuracy than overall length.
