Are there any differences between the Winchester brass that have the following head stamps: WIN, WW SUPER, WINCHESTER.....or are they all the same ?
THANKS !!

They're definitely from different lots, and may vary in capacity. I'd keep them segregated by headstamp, at a minimum.

when i was stocking up on brass a few yrs back i'd get once fired brass from vendors at gun shows. i always asked if i could go though and pick out the winchester brass from the lots of brass. i like ww brass better and my brass mostly all matches that way. i've always felt winchester made better brass for center fire pistols.
