Can only echo what others have said. MTC are not really designed to be used on large bore rifles in my opinion. They are good for what they are designed for. I love the christmas tree reticle. I have had two. Now replaced with secondhand leups. it you want to shoot deer then dawn and dusk is a priority and the MTC will not cut it. If your lamping then yes you can use it if your doesn't white out at highter mag, although with discussions with others this may be because you eyeline is critical so if it does white out try moving your head a bit see if it works better.
