I am not sure if this is appropriate. This is a bullet casting forum.
I am deluged with Berdan Primed brass! I have figuired out how to modify the Berdan Primed brass, and had it work.
Can someone make a fixture for me?
Berdan Primers are .216.
Boxer Primers are .214.
Being a jeweler, I used a #3 drill, .213, modified into an end mill. This removes the anvil. I use a #3 drill to make a starter hole, and finish with a #7 drill making a flash hole. I use a ball bearing to swage the pocket to .214.
It has worked for me so far. I have had no primers eject on firing.
Does someone, or can someone make a fixture that would incorporate a removeable #76 drill that doubles as an end mill. The fixture would need to incorporate a depth stop and be 1/4 shank. I use a Foredom handpiece.
All that needs to be done is level the anvil, and drill the flash hole. Making the outside of the mill acts as a safe edge and merely burnishes the walls.
Food for thought.
I would then want a "die" where the die acts as a solid stop inside the case, and a ram fits in the position a shell holder would. The end would need to be shaped like half a ball bearing.
In practice, the inside of the case would be against a solid ledge, over the flash hole, and the ram would act as a swage with controlled stroke limit.
I am unable to get Berdan Primers.
