i trimmed some 223 brass to 1.750. When chamfering and deburring, i did a little too much and a few cases ended up at 1.742. What is too short? Any issues with these. Thanks.

Close enough. Happens to me now and then too.

I don't have the trim to lengths to confirm but that's next to nothing & you will probably find new brass even shorter. Just load & be happy.

Are there opinions as to what is too short? Thanks.

Yeah; if the necks are too short to retain a bullet you'll need to toss 'em.

223 case length is 1.750" -1.760". I trim my cases a little short,1.745" to figure for a little stretching when resizeing.

I also find that alittle shorter is better for me, I trimmed 10 of'em and shot them with my pet load and the grouping was alittle better than the norm I thought I was taking extra special time so retried it and a little faster in sets and BINGO.... they were tighter I am looking at the necks and base to ensure I'm not asking for trouble none to speak of so I am sold....

I have shot on brass much shorter than that :)

I resize 'em to 7.62x25 Tokarev.

Just cut 'em down to 1 inch exactly & run 'em thru the Tokarev dies.

Don't toss em, save them for reforming into 221 Remington Fireball.

SAAMI lists a minimum length of 1.730" MrCountyCop, 1.730" is what is online here> http://www.saami.org/PubResources/CC_Drawings/Rifle/223%20Remington.pdf :)

If you took .008 off the length when deburring and chamfering, you WAY over did it. :eek:

They are not too long, but that is not be what I would be worried about.

Cases need a light deburr and chamfer, If you take even .001 off the length you way over did it.

That shouldn't be an issue. But what might be is how far you reamed and chamfered which sounds pretty significant. Getting the mouth too thin, like almost razor sharp can weaken it enough to start causing split mouths. Just a little tip on this, ream and chamfer just enough to remove the lip or ridge created by trimming, no more.

Most excellent. Live and learn.

As gamestalker posted, you just need to remove the sharp edges on the case mouth. :)
