If you are looking to purchase some top notch cast slugs, I will suggest Montana Bullet Works. They are insanely quick to ship, good folks, and produce a fine slug.
My buddy ordered from Beartooth bullets in October of last year and just received his shipment notice. When he called to ask about his order they shrugged him off. He won't order from them anymore, and I can't blame him.
I'm not bashing Beartooth, but if you want them sooner than later, Montana Bullet works is the way to go.
