Thanks for all the suggestions guys. That video was very helpful. I'm not going to worry too much about the load. I'll pick something simple and pattern it so I know what it's capable of.
I'm going turkey hunting for the first time this fall and I'm not sure where to start on loads. I have a Mossberg 500 with a 20" barrel and X-Factor xx-full choke tube.
I know I need to pattern a few different loads in my gun before I go out, but honestly I don't even know which ones to start...
