Name this bullet, when can I get a mold for it.

Long story short I got some 510 wells loaded ammo that where loaded with this bullet. Hell or high water I can't find anything about this gas check .510 450gr (bare no gas check) bullet. Does anyone know where I can find info or a mold for this bullet. Thank you guys.

Accurate Molds. If he doesn't have it I'm sure he can make it.

All else fails, Tom at Accurate can make a copy of that.

I just looked in my Lyman handbook of cast bullets the one with the Sharps rifle on it, and on page 165 it looks like a gas check version of 515142 that was made for the 50-70.

I need a good size .510+ GC mold for my 510. I have never fired these out of the gun so I don't know how well thy work.
