I reload for my SKS and love devoping loads for it. It can be turned into somewhat of a tackdriver. I have loads that are consistant 1-1.5MOA with iron sights at 100yards with SKS. Can't do that with milsurp ammo!
Besides, has anyone tried to buy 7.62x39mm ammo lately, everyone is sold out, so reloading is a great option. You really can't push much out of the cartridge ballistically speaking, but you can load up SP's for hunting and accurate ammo for the range. Plus, its good time at the reloading press.....what's not to love about that!
