There was.. Golden Bear or something similar sounding that at one time, who made 510 JHP's but I think they're no longer around.

Hello Tiggertate.

What are you looking for a .510 bullet for?? a pistol or a plinking bullet for one of your rifle projects.
One thing you can consider is swaging up a smaller bullet.

I made a die to bump up the Speer gold dot 50 AE 325 gr HP, to shoot in my 505 Gibbs at .506 diameter.
I have a 50-110 project in the works, and will be playing with the same bullet at .512.

This method is for a light wieght plinking bullet and would fine for deer. I would not even consider it for any thing bigger that bambi.
