I would Use a JP spring (7%) with a standard or light weight buffer.
Or use a heavy buffer with a standard spring.
What did it feel like with just a heavy buffer and standard spring?
My 16" mid-length gas is a smoother shooter with a 9mm buffer and a standard spring than with a standard weight buffer and standard spring.
There was some video slow motion showing that heavy buffers, and especially the 9 mm, could result in bolt bounce.
