anyone have a mossberg 500 or 590 shotgun?

Just a word to the wise about using this or any shotgun as a home defense weapon. You don't want to use 00 buckshot because at inside your house range it will go into what you were aiming at and have a very good chance of going thru walls and doors and hitting things you weren't aiming at, especially if you live somewhere with thin walls and doors (like an apartment). You can do just fine with #4 thru #8 bird shot and cause less collateral damage. Also be warned, shooting a shotgun indoors without hearing protection is an very unpleasant and disorienting experience. It will temporarily blind and deafen you, unlike in the movies. If you get a chance, go to an indoor range and take a shot with no ear muffs. Ouch. It can make re acquiring your target if you missed a bit harder.
