Ultimate Black Widow I showed yesterday, the gun is sold. But we are planning on building another couple of guns. We have the next one about half finished.
For those asking what load we used, we used 12 grains of Trail Boss powder and a hard cast gas check 375 grain bullet. That gave us the power of a hot 44 Magnum. If you don't reload then my suggestion is order some 500 Special ammo off the internet. The gun will handle full power 500 S&W ammo but why beat yourself up. Shoot the Special ammo at the range and if you go hunting dangerous game, then load up the factory 500 S&W ammo.
