Which brass to keep?

[Hoss in IL]

ellison, I've reloaded all of those. I haven't had any problems so far. I used to do the same thing you did, separate by head stamp. Not any more, too time consuming and from everything I've read and have been told, it doesn't make much appreciable difference to spend the time doing it. But, if it makes you feel like you'll be producing better reloads, go for it.

You might find that some of the brands have tighter/looser primer pockets. You'll feel the difference when you seat the primers.

You can take your calipers and measure a random mix of different brand case lengths to see if you have a wide variance in case lengths for setting up your dies. That would be the only reason I could see to separate brands.

Take this with a grain of salt, I've only been reloading for a little while.

ETA: I did have some problems with Remington brass. I picked up some cases from BRAND NEW +P hollow points that I had just fired and noticed that the cases were cracked from the case mouth to about halfway down the case. I looked at the rest of the UNFIRED cartridges in the box and out of the 42 rounds left in the box, 18 of them had hairline cracks in them (before even being fired). So, it pays to inspect your ammo, reloads and brand new factory rounds too.
