Your best weapon is your brain. Don't leave home without it.
Thoughts: Justifiable self defense.
Explain: How does disarming victims reduce the number of victims?

From a reloaders standpoint I load 00 and #4. both stack well in a 2 3/4" shell without the need of fillers to even out the load. in a 12 guage hull three 00 shot will just lay in the bottom making a nice tight triangle, and three of thos triangles will stack up to just fill the hull and make a nice crimp. the #4 works the same but with multiples of 4. #4 also works in 20 ga but in multiples of 3 and a 3" hull. It just works out to a nice full shot column. DR
