What i try to do, and it sounds stupid, but having some extra fuel on the way down isn’t a bad idea, for example if I have a Mun mission, and my Lander still has some fuel, I will renter the atmosphere, and try and burn off a little bit of speed, if I can. Then, I deploy the parachutes. If you can, try to land, on land, since the heat shield could help you. Hope you solve your problem, have a good day.
