One of my sources for .318 bullets are Hornady 170 gr. .321 dia. Win. 32 Special swagged down thru die (tube with steped hole). One dia. to guide .321 bullet other to swag down. I use arbor press to push thru with guide rod. Any machine shop could make die. My 32 Spec. swagged bullets are accurate and open good at lower vel. I also use Rapine 319195 and 321195 (195 gr.) to mold my own.
