Here's a YT video showing the difference between 1, 2 and 4 MOA dots. At turkey hunting distances, I think visibility of the dot will be a greater factor than the dot occluding your target.


At 50yds, a 1 MOA dot covers a .5" circle (.5236" to be exact-er)




I just put a Burris FastFire III 3MOA reflex reddot on my boom thumper.
