my question is if i wanna shoot deer at or less than 50 yds would a red dot scope be enough?
The complaints on the cheaper ones (<$50) range from "wont hold zero" to "cant see the dot in full daylight"
The complaints on my Bushnell Trophy ($100) were that the poa changes with selecting a diff recticle (I have not tryed this yet) but the dot is clear and bright at a low rheostat or brightness setting even in the summer sun. My Bushnell Trophy has only had to survive a couple hundred shots on top the .44 mag and is holding it's zero well.
Next in line IMO would be the $135 Ultra dot or perhaps $185 for the Ultra dot four dot (No Complaints that I could find with again, the ability to hold zero & dot brightness being keypoints)
Other complaints in general are that the dot is too bright in the dawn & pre-dusk conditions...my bushy has the ability to change the recticle from Red to Green but I believe that the Red only would work well in either
The bushy or the Ultra on the low setting.
