HeavyLead comes from two different hobbies that I enjoy.
One, is Scuba diving. Being of large frame and well insulated, I find myself rather buoyant. This requires about 16 pounds of lead shot weight to achieve neutral buoyancy in the water with a mostly deflated "wing", or buoyancy compensator air cell. Of the members of my diving team, most others use between 6 and 10 pounds of weight, hence...HeavyLead.
Secondly, I like to take part in competitive defensive pistol shooting matches. (I am no professional by any means) I prefer the .45 acp cartridge for many reasons when most other shooters use the 9mm or .40 SW for the reduced recoil, cheaper cost, etc. Again, because of the larger bullets...HeavyLead. I have enjoyed reading other responses to this thread.
