That’s the dilemma for the first couple shots.
Do you want something that will go through the sheetrock... or something that will throw a bit of a pattern?
I have a sheetrock wall between me and the hallway. Hate to go too light on the first load.
My mosseburg 500 is carrying 3 rounds #4 buckshot then 2 rounds 00 buckshot. If bad guys have already entered the house, racking the pump tells them where you are. Just the thunder and “say goodbye azzhole” is what’s in my bedroom.
