I finally decided against reloading 10mm so I added to my list the 10mm brass I've accumulated over the past few years. Non of the brass was ever reloaded by myself.
I never ended up buying any guns chambered in 10mm and because I already load 400 corbon I don't really see a need to start reloading 10mm. So that's why I'm wanting to trade away the 10mm brass I've accumulated.
