I want to start reloading 7.62 x 39.  I have a 550, and have been reloading several pistol and rifle calibers.  However, it appears that Dillon does not make a die for 7.62 x 39 and I am coming across several different sets by other manufacturers.  Some are 2 die some are 3, and each manufacturer has different steps at each die.  Can anyone please provide info on which specific die set is best for the 550.  As well as any pointers for someone new to reloading this caliber.  I would rather not find out the hard way.  Thanks...
