408 Cheytac, 500 Maximum

[Orange954]

I have recently come onto some 408 cheytac brass I believe most is new, and some dies for it,
as well as some 500 maximum brass thats new,

anyone know much on these and if I should hold on to them or push them out, as I wont be able to find anyone that shoots it later on. Both seem to be very rare already.lightbulb

I forgot to mention the 500 maximum or refered to as .500 Linebaugh Maximum or long, is Hornady and the 408 Cheytac is TTI which from what I have found out is no longer in business but suposed to be the best you can get.
