I have approx 3000 5.56 brass that I have collected for years and am finally ready to reload. I haven't done any yet but I am all set to go.

The question I have is about case length. Many of the cases are signifigantly shorter that the 1.750 case length that I see so many people talk about and some are longer. My measurements range from 1.736 to 1.762 or so. How much does this matter for plinking ammo? Should I just trim the long ones? Should I throw out the very short ones? Any help would be great.

BTW, I will be sizing/seating with one of the new RCBS AR series die sets that is supposed to properly taper crimp varying case lengths.

Thanks!!

case length is meaningless until you resize the cases, then measure, then trim to 1.750".  Cases that are under 1.750" after resizing are still good to go

You haven't sized any brass yet from what I understand, so case length is irrelevant at this point in time, when they're sized they will likely stretch a little more.  

I'd not worry about cases 1.736", they will also stretch. Uniformity in your brass has everything to do with accuracy and reliable function of your weapon so it is good to be concerned about this.

Cases should be between 1.750 and 1.760 are safe to reload.

Any case longer that 1.760 after sizing must be trimmed.

Sort cases by headstamp, size, then trim.



I suggest you invest in a how to book for beginners that will explain the reloading process.

Also do some reading at the top of the page, FAQ'S and Tutorials.

Do some research, then come ask questions on what you don't understand.
