So I am in the process of moving from a house to an apartment. My go to HD option is a mossberg 590 and I'd like to continue to use it that way especially for my girlfriend when I'm not home as she is proficient and comfortable with it and not very accurate with my pistols. Three of the apartment walls are brick with nothing on the other side. However the fourth is concrete with another apartment on the other side. That wall is actually my bed backs up to so it is unlikely I would ever have to fire in that direction. Just to be safe I want to go with a round that is less likely to over penetrate but still effective. Right now I am using remington express 00 buck. Thanks for any suggestions. If I left out any important info let me know.
