True to his word a friend brought me eight 5gal buckets of brass, various calibers, pistol and rifle. The LC .223 brass appears once fired
as the primers are still crimped but almost ALL of the Federal .223 I've checked appears under trim-to length some by as much as .014" !!
 Is this common w/ Federal brass? I've never reloaded Federal before so it was a surprise. So, scrap it, or do folks reload this under-length stuff?  I have more than enough LC,
Winchester,and Remington brass for my .223 needs.

Send it to me.

A lot of people haven't had good luck with Federal brass, I load it with no issues.

It probably won't ever need trimmed.

I've shot Federal as short as 1.737 before with no issues.

Resize it, load it, shoot it.

I have a ton of it. Same thing. It can measure anywhere from 1.735-1.741. I haven't used it yet, but I'm sure I will one day.

From what I understand the primer pockets loosen up pretty quick.

FC brass is always short. I sell or trade any I get.



Keep and load the LC.

If you shoot blackout use it for that.

I've loaded FC cases that were as short as 1.730....They shot fine.

FC brass has a terrible rap, I think it is due to the older non-crimped cases. In my experience they keep tighter primer pockets than RP brass.

YMMV

ALL fired brass is shorter when measured. You must resize it first, then measure it. The case body expands to fill the chamber upon firing, this causes the length to shorten. When you resize the case the body gets squished back close to it's original dimensions which causes the case to grow in length.

Even after sizing I find Federal to be way shorter than the rest. Still shoot just fine loading cheap fmj for plinkin'.

When using "X" Dies, RCBS recommends trimming brass 0.020 short. They work fine for me.

I'm getting 2" groups on my 3rd loading of Fed brass, using X die. BTW: at 300 yds. with AR15.

Beat me to it.. Always measure AFTER you resize! Same thing with headspace measurements.

CSB: When I first bought my Hornady Headspace gauge kit I thought I screwed something up because I setup the die, resized the brass, and the headspace grew! haha.. I was trying to figure out how in the hell bumping the shoulder could cause it to increase! Finally realized my derp and lesson learned. Now I always measure after resizing.

I've found Federal brass to conistently be short after resizing.  I load it for plinking rounds without any problems.  I've also had the stop on my trimmer shift and trimmed a few pieces of .223 down to 1.730 by mistake.  Again, loaded and shot without problems.  There was still enough neck to hold the bullet.
