I think I'll wait on the Youtube reviews before investing Bob bucks in cast iron bullets.

Laser Cast Bullets are hard bullets made to be shot at higher velocities than most commercial cast bullets.  I load one of their gas checked bullets in 30-30 cartridges and get good accuracy.  Their handgun bullets are too hard for CAS main match ammo.

All internet info I see refers to cast Lead alloys not Iron.

Has to be a typo, Cast Iron would be a recipe for gun explosion.
