I originally put a Nikon Coyote Special on my Colt LE6900. I like the glass and have a 100yd zero with it. I use it for target shooting and coyote hunting and it does what it's intended to do. The area that I hunt in is also ripe for hogs. I did not feel 100% comfortable shooting a charging hog, a situation that I hope never arises, while using magnification through a scope. For that reason I mounted a Burris FastFire III red dot on top of the scope so I could have both eyes open in the event of fast moving and up close action. I feel comfortable with the true 100yd zero on the scope but a bit torn at what distance to zero in the red dot. I'm torn between 25, 35, or 50. Being a 4" difference between the bore and the red dot, I do not want to sight it at 100 also as then I don't like the idea of having to aim high at short distance because though true, it isn't the first thought the brain would have in a pressure situation. I want to truly be more reactive with the red dot if needed. I look forward to any tips and experience that might get passed along. Thanks!
