My wife and I had a little scare the other tonight, she thought she heard the door open, I went to check thank God it was nothing but I realized I wasn't to familiar with my 12 gauge Harrington and Richardson shot gun and I was just wondering what type of Ammo I should use. Right now I have a bird shot but is this the best ammo for the gun? Also I have a 6 round holder on the butt of the gun and a flashlight on the lower barrel. I'm not a big fan of alot of unnecessary attachments, is there anything I can do with or without?
