As .318 bullets are hard to find here in Germany I took a new Volvo truck wheel bolt with a 7/8x14 thread that cost me only 6 Euros and got it bored through by a toolmaker neighbour into a very long conical hole reducing the hole diameter from .323 under at the beginning to .318 diameter for the last inch before they pop out then I guessed that standard jacketed .323s should be drawn down the required 5 thou (that was the concept), But jacketed .323 bullets were just too hard to draw down so the idea was shelved. I also had 300 of these (web site below) H&N .323 heavy copper plated lead bullets "they do not offer them in .318" diameter and I have just tried drawing them down. I lubed the bullet with a Q tip of standard sizing lube and 30 bullets have reduced perfectly down to .318 diameter without any undue pressure on the presses arm lever and the bullet base is still the same shape as it was before sizing. Lee do not offer as standard this diameter die.
