Wow that is a hard question,but I use a lot of winchester and federal but also load about every brand( but WWC and A-merc), but do keep them sorted by brand.When I started reloading I tried to keep them sorted by times fired but found was almost impossible to keep them sorted.The more you shoot the harder it is to keep everything straight.
I am sure that most of the winchester that I shoot is mostly WWB.For me I load on the lighter side and very rare to have a round split with the brass, now the nickle they seem to wear out faster
