7.62 dies...
I personally use Hornady dies to load for my SKS and CZ550 carbine. The crimp they provide is more than adequate for the recoil that the round generates in the SKS, and moreover the CZ550 carbine which recoils more in the 270/30-06 class due to its 6 lb weight. Hornady dies (as do all I believe) come with both the .308 and .310" diameter expanders.
My 7.62 load (for both) consists of close to a max load of AA2015BR (cant remember the exact weight--Im at work and cant check) winchester cases, CCI standard primers behind either a Hornady .310 123 grain interlock or .310 123 grain Vmax. In both guns, either load is interchangable and hit at the same point of impact. The CZ is a genuine, repeatable 1" gun at 100 yards with 3 shots using a Burris 4x20 short mag... the SKS with open sights will consistantly strike within a 3-4" circle @ 100, if I do my part.
Hope that helps!
