I use both sight's ,I use my Spott Hogg for 3D and I use my Cosmic for hunting .I find while hunting I'm set for 30yrd shot and anything inside doesn't effect it too much ,but I agree you'll need to compensate a little up real close or just outside the 30yrd .If the animal is say 40yrds + then you'll have time to make a little adjustment ,but most of my kill's have been inside the 30yrd mark and have yet had to make any adjustment's on my sight .
