I, unfortunately, bought a 5,000 round box of Thunder Bolts.
This was the "Dirtiest" ammo I've ever run across. After 10 rounds in my Pistol, the slide was almost glued from residue to the point it would not pick up and chamber another shell. I also had many misfires, failure to ejects and probably every problem you "can" have. I ended up giving the rest of the case away to a friend who had just bought a single shot for his son (for his "1st" real rifle).
That's the only good thing I can say about this, it helped introduce a new shooter and a couple of his friends into the Shooting Sports.
