This loading was devised by Giovanni Todescato and it was tested with a pressure gauge.
It is an excellent slug as You can see, it has a low pressure for this kind of cartridge (750bar) with a hight velocity 470m/s.
It was tried with wild porc with great results.
We have made a round edge clousure with a Steel roll crimp model: Pal C4
As You can see it is very good
Its finished height is 58 mm.
