This loading was devised by Alex 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 (560bar) with a hight velocity 460m/s and keep clean the bores.
It is great for Championship.
We have made a round edge clousure with a Steel roll crimp
As You can see it is very good
Its finished height is 58,5 mm.
