I’m as big a fan as any normal person of a lead hose hand held weapon. However, if you are in a defensive situation that calls for that much lead downrange, you should consider truck mounted chain fed weapons and grenade launchers instead. If the race war starts or the EBT system is down for long, these may come in handy on the urban borders.
And what percentage of us can afford such exotic weapons in Obama's economy? That's pie in the sky for most working folks.
