Is a mil-dot reticle practicle if you have a rangefinder? I was looking for a new scope for my .300 win I have never used a mil-dot. I have heard that scopes with target knobs can get in the way while in a rifle scabbard so I thought I might get a mil-dot and just assign a point of impact for each dot. I us this rifle exclusively, I hunt here in MI but plan on going west to hunt. Thanks Chain
