Like Catfish said, unless you're loading for competition there isn't much need to go through the trouble of sorting brass. You'll generally find that just about any assortment of good quality commercially prepared brass (Winchester, Western, Remington, etc.) will get you into the 1 MOA range and that's plenty good enough, even for long range hunting out to perhaps 800 yards. That assumes, of course, that your shooting skills are sharpened to work at that range. Once you get past 800 yards 1 MOA, IMO, isn't quite good enough and you need to get closer to 1/2 MOA with those same skills.=... I keep getting told that I need to sort my brass and was just wondering what brand people prefer and for what reason.
