Maybe primary inductance was not big enough to reset core fully. With 1 forward topoly core doest get hot i think
First transformer has Lmag 1,5mH
Eq from presentation : 300/(0,5/(0,1/50000)) = 1,2mH ???
It should be rrght
Some/much of the ringing is from the long wires to the transformer.
Copper loss: It looks like the winding area is not full. Your outside winding is two wires and you might have room for 3 wires.
Core loss: You can try increasing the turns. This will decrease the volts/turn.
