I don't know if the ammo names at FireQuest are the best, but if you read the descriptions, you'll get a good laugh.

For example, the "12 Gauge Terminator X" is described as:
"The lethality contained within the hollow core slug of our terminator 12 GA almost can't be advertised. Upon impact, this slug mushrooms and expands to nearly two inches, stopping the slug from totally penetrating your objective. This rapid expansion forces the dozen of tiny pellets to spread through your objective like a cancerous disease, opening an area at the impact point equal to a softball. The cavity created has the shock effect of 95%. That means only 5% of any living being could survive this kind of hit. 2 3/4" round"
