Good news:
Montana Bullet Works is back and seemingly better than ever.
Home page - Montana Bullet Works - Custom Ladle Cast Bullets
Looks like they have all the LBT designs and many others at prices lower than Cast Perf. or Beartooth.
Going to have to try them out.. maybe with the unusual 220 OWC-PB 44.
Could be good in the 44 special as a SD or souped up a little as a rural carry load.
