I have tried calling and e-mailing Buffalo Bore Ammo to see if they are using Speer Gold Dot components to make their .45 caliber ammo. They do not get back to me. I know a few years ago they were using Speer Gold Dot components, but I have heard a rumor that they may be using Montana Gold components now. Does anyone know what Buffalo Bore is making their .45 caliber ammo with today? Thank you for your time and attention. Time to grab a cup of coffee!
