They are 2.5 Super X hulls. They are not brittle and no tarnish on the brass, no tears inside on the ones I examined. Along with them is 4 unopened boxes of assorted fiber wads. Also several bags of WW,Rem,and fed plastic wads, 2400 and 296 powder, Fio primers and some Herters for the older Rem.
I have the 2nd edition lyman so I need an earlier version.
