Mid length gas on an 18" barrel? I'm guessing your setup is way overgassed, which is completely throwing off your action's timing. Shortening the buffer spring just made it worse.
I'd get either a Sprinco RED spring or a H2/H3 buffer and try again. If neither of these work, you may need an adjustable gas block. Also, try some factory Hornady ammo to rule out your handloads as a contributing factor.
