| I was wondering, I already sort my brass for my 308, how many of you sort your brass for .223?? Since my 308 is a bolt I am not too worried about a semi auto loads for that, but for 223 I know it is different. |

Depends on the brass and the load.
AR loads, LC(no nato cross), WCC, and other mil brass are used as blasting / practice ammo, and loaded with 55 gr FMJBT's. LC and other mil cases with nato cross I use for my SS-109 loads. I can then tell which FMJBT bullet, 55 or 62 grs is loaded in the case by the headstamp with this system. Win cases are used for target loads. PMC is used for test loads. PMP has to be sorted out and loaded separately. It is very heavy brass with less internal volume. I load it at least 2 grains lighter than the same load in Win cases. 
See how much thicker the web is on PMP brass. Rem cases are used for my Contender loads. FC cases are used in my 223 bolt rifle. Other cases I sell. My OCD system.

For practice ammo it really doesn't matter. The internal case volume of almost all the common brass is very comparable.... with Mil brass having slightly more capacity (thanks, Molon).
I only sort by headstamp so that I know which ammo requires specific case prep procedures like crimp removal. After that it becomes once fired commodity brass. |

I sort crimped & non-crimped until I process it...then it all goes together. I only load for targets right now so this works good enough for me. I do keep once fired 5.56 brass that measures exactly 1.750 (un-trimmed) in a seperate bin for future use when I play with my 68 gr Hornady's  , just because.

For ME............it would depend on how much I cared...........
That is............ IF it's gonna be Match ammo.........I'd care enough, to get as much uniformity that I could. IF, it's just for plinking............as long as I keep it safe, goes downrange and hit's the black part, that good. "Good enough," would be getting the ammo to group decent. What's decent? So, you see.............I haven't mentioned a group size. That's because what's good enough for me..............may not be good enough for you. You might use a fancy hi-powered scope and sit at a bench..............I ususally don't. Aloha, Mark |
| I sort because the brass neck thickness of the different types of brass I load is different. Lapua being the thickest. This requires different neck sizing bushings to achieve the neck tension I prefer for my AR. This is primarily a function issue for me not accuracy. |

I do and this is why.
In my limited experience I have found what is a great load in one brass may not be in another: LC brass loaded to accuracy (well within safe margins)/Same load in another brass(forget which) showed signs of overpressure and I had to pull 8 bullets. I re-worked the load in the new brass and ended up with a whole different load to get the same accuracy. All things were the same: primer, bullet, powder, and rifle. Untill I have enough experience with and testing on my different sets of brass Im staying on the safe side. |

Based on what I read above, I must be OCD. I sort everything, and only start loading with a new headstamp when I have enough of them to be worth my while. Then again, I also track how many times each set of cases has been fired. I have a bunch of PPU 08 and Remington and a few hundred LC 08. I track these by group. Range pickup all goes into a single bin and when it's full I'll sort it out. Almost all my cases have now been fired twice. (I haven't done the second firing on the LC yet). I have a seperate bin of PPU that I use for match loads. Other than match loads, I use the same load in all of them (24.5g TAC, 55g FMJ). I'm mostly just curious to see how many times I can fire the cases before they're no good anymore. I've already ditched several PPU cases, but only one of them had a cracked neck (the others got screwed up in my press when I first started reloading and was making mistakes!) |

But I can't imagine a load in LC that would be significantly different in another flavor of brass. If I remember corectly the primer were blown/pierced. I may have been wrong too but my rifles are too expensive to screw around. My face is kinda cheap but I would like to keep that. I ended up with a load that performed better anyways. |
