When I'm using a caller, I like and use what you got, the EOTech on a RRA M4. Yotes are smart so I use a dead (fresh, sometimes w/ a string so I can move him) rabbit for them to see and like to get them close as possible.
As they're thicker flies up around the chicken-houses at the farm; sometimes they pour over the rise in a pack of 6 or 8. I wait till they get close and begin to get wary, then drop one with the best shot I can make, hopefully inside a 100 yards or closer, then the "red-dot" comes into its own as I like to go to town on the closest to the one I dropped as he's likely frozen for a split second. On occasion I hit him, but the rest are for sure gonna be "beating feet", so I have some fun with them.
Note: yotes invaribly circle around to come at ya from down-wind of the caller and bait, so keep that in mind, and be mindful of your back-ground, 'cus at times you can get carried away and ya don't want no rounds going off the reservation. There are other houses around the farm so this is a concern for me and I watch my set-up based on the wind and homes nearby (1/4 mi or so), but when set-ups right I have more fun shooting at the ones I miss than the one or, if I'm lucky, 2 that are downed. (and Dad complains about me starting wars [;)]
While a scope may get ya able to make the first shot at a further range, chances are it'll not be fast enough on target to have the further "fun".
