Not being much of a turkey hunter I bought it for both home defense and for the fact that if the Libs get their way then this particular shotgun will be illegal in two years.
My question is, for home defense what type of shotgun rounds are ideal? Bird shot? Buck shot? What's the difference between the two? Right now all I have are "dove load" shells and some spare slugs.
Also, can one take a shotgun (with slugs) to fire on a rifle range? Short of calling a specific range anyone have any experience doing that?
And finally does anyone know where I can find a shotgun light and holder in real tree camo? Is there such a thing or will I have to settle for black?
Thanks all
