Around '82 when experimenting with making home grown bullets bases more resistance to plastic deformation and having softer noses, I'd stand them up using a steel pan in an electric oven, calibrating the setting of the oven to the point that slump* didn't occur. The steel had to be heavy duty enough to not jump around when water was added to the pan at the end of the heat treat and the pan had to be leveled for bath flow. The result was better tails and better noses. It was an interesting technique that yielded satisfactory results, but ultimately I opted for creating a cartridge design that was friendlier to cast rather than working around someone else's jacketed bullet mistakes.
*At the boolit base first due to heat transfer from the steel pan; dumped a lot of heat into the small area of the bullet base and the weight of the vertical bullets exerted most there.
