I'm looking for a book with more information on load selection and use, information about different manufacturers loads, slug information, accessories, shooting techniques, etc. I don't need info on different types and brands of shotguns unless it pertains to why a double barrel might be an advantage over a repeater at times. I already have a Winchester Defender, so I'm past the selection phase. I don't want a standard "shotgun" book because they always talk about chokes, sporting clays, etc. I'm looking for a bucksot, slug, and combat book not loaded with BS. I've seen several advertised online like two by one guy called "Streetsweepers" and "Super Shotguns." Another called "Combat Shotguns" by some other guy. One called I think "The Tactical Shotgun" by Gabriel Suarez. I already ordered the Gunsite "Tactical Shotgun" video because I found it on sale. Now I'd like to know which books are good and which are bad if possible. Your help is greatly appreciated and I thank you in advance.
