This company must have bought out Blammo Ammo, who used to sell the same stuff back in the early 90's. They didn't even change some of the wording of the descriptions from what Blammo used to use.
Here is a scan of an old pic of a friend shooting the "Dragon's Breath" round. Appropriately enough for this forum, it was shot from my H&R Topper....

This ammo didn't damage the bbl, but I only shot about six rounds of it. We did start a small grass fire with it the day the above pic was taken. Lucky it was a rainy day.
