I recently ordered a Leupold Mark 4 4.5-14x40 Target. It's the same as other Mark 4 scopes except it has target turrets and a duplex reticle. I will be mounting the scope on my 700P .300 WM. I'm having second thoughts that maybe I should've gotten the M1 turrets and mil-dot. For all intents and purposes does anybody think the M1 with a mil-dot reticle is really necessary/worth the extra $$?
