I used to have an old saying I told newbies at work when they were about to make their first presentation to a group, Keep everything in your wheelhouse, only talk about what you know and know what your talking about", if it gets outside those lines that is where you'll embarrass yourself".
So my advice on guns is know what your shooting and know what your shooting it with, anything outside of those capabilities will leave you mad and embarrassed". Any gun and load will work inside of it's capabilities. Heck a couple years ago I decided to take my old Improved cylinder by full choke, 2 3/4" chamber O/U with high brass pheasant loads, just because it's an old classic and my favorite all time gun. I killed a gobbler opening morning at 12 yards, I let him walk right to my lap because "I knew what I was shooting and what I was shooting with". My advice is don't get hung up on guns, there are bigger things to learn turkey hunting.
