I'm not sure I understand. Did you check the drain with no rectifiers (or with the 12v supply so low the amp would go to 50%) with the scope grounded to the source terminal of the FET?
The ringing could be either too little deadtime or a bad snubber.
Don't pull the rectifiers to check but you might try reducing the 12v.

Initially when the ringing was there I had the probe ground on the neg terminal of the amp. And the probe on the drain with no inductors. After I added the inductors I checked again. It was gone. But that was still at the 13v. I'll do as asked soon as I get this inductor out and fixed.
