I currently shoot pistols but I don't yet own a shotgun. I was considering buying since they tend to be cheaper for home protection as well as range fun. But I have a few questions: 1. What are good, reputable shotgun manufacturers? I always hear about Remington, Benelli, and Mossberg so I assume they are the best but I'm not certain. I currently own a SIG Sauer P226 pistol so I'd like to get one on par with that quality if I do end up buying. 2. How expensive is shotgun ammo? I checked on a few websites and it seemed that buckshot is typically $1 per cartridge which seems expensive but is that what people usually practice with at the range or what? 3. Is it true that shotguns don't take much practice for self-defense when using spread/buckshot? Thanks.
