RE: 870 slug problems
You know I know alot of people having trouble with this. Here's the way I think of it. I think of it very exaggerated. In other words, I think of it, if I was wanting to shoot the furthest and hit the highest, my gun would be at a 45 degree angle pointing up, but wouldhave to raise my sight a whole foot, but if I wanted to hit the ground right in front of me, I can't lower my blade enough.
Same with bow. Except opposite.
