Yes, this brass is reloadable.
Bill, most Winchester brass can be reloaded 3 to 4 times before it needs softening, and trimming back to C.O.L. The number of times a case can be reloaded and is not a set in stone, sometimes I'll get the third reload and I have to trim it back. I suggest that you sort the once fired brass into at least two lots. The first lot is brass that doesn't need to be trimmed.
