223 brass out of spec after full length resizing

[ronas]

I have some 223 brass that is out of spec after I full length resized it. It is 1.745". Is such brass generally disgarded? I use this brass for precision shooting out to 800 yards so it's loaded to max charge to a little above the max recommended in reload manuals.

Trim it! I always trim after I resize my brass for rifle.

Does not need to be trimmed it's to short.

It'll load just fine if you FL sized it.......I've picked up LOTS of range brass that was under 1.75 after sizing. I dont recall which brand (remington?) but were consistantly short.......Might not be the best for a precision load, but it will shoot.

I trim to 1.740" and sometimes you can find LC that is 1.735". Trimming to 1.740" gives me a more consistent crimp on the canalure because I find once fired brass to be on the short side. Plus I wouldnt call it out of spec. 1.750" is max length, not all brass will stretch to it just because its been sized.

The brass is probably not going to help you on accuracy, but they are safe to shoot. Depends on what firearm you are using, you might not notice any different in accuracy.

I reloaded brass that are a little too short (1.740"), and they shoots sooty. The top 1/3 of the brass is covered in light shoot.

That's a good thing, a couple of extra loadings before you have to trim them.

It's common for Factory cases to be a tad short, Federal especially so.

Actually 1.750" is the trim lenght and 1.760 is the max lenght.

You can still use the brass. After a couple of firing it will be longer than 1.745". It may not be precision shooting brass till you get the length you seek.

It does not matter, as .005" has no affect on accuracy. Trim them all to this length if you worry about consistency.

I shot almost exclusively SMK 77s and some SMK 69s and they have no cannalure.

I may save this shorter brass for 62 grain bullets as this is now my shorter range blasting ammo. I don't like to shoot the 55 grain stuff since it's so inaccurate in my rifle.

Some guys are using that RCBS "X-Die" and trim to below the "trim to" length. When they re-size the brass, it won't allow the brass to go out of spec. It actually forms the length down with each Full-length sizing. If they're shooting a semi-auto and their brass goes flying, you might find some of that brass at the range. It sometimes takes a few firings to get the brass back out to the "trim to" length; maybe 2-3 firings.

Possible explanation...

If you are shooting 69's and 77's out to 800 yards, you have MUCH more to worry about than a .005" variation in brass length.
