Yes you can handload the 308 ME, I am sure dies will be available. Good
luck trying to attain the same velocities the Hornady cartridges can attain though. Be sure you're insurance is paid up if you try. I would
find it difficult to believe Hornady didn't apply the same technology they
attained in developing their Light-Magnum product to the 308 ME.

No my .307 AE didn't have a trigger job, just carefully built handloads.
