Certainly tweaking LRD dots with mag changes can be done, but it is not a very precise way of making hits. The practicality of using a reticle starts to go away as the distances increase. I have an LRD reticle scope and I like it, but a mil/mil scope w/ turretts turned to arange POI where the crosshairs lie is a much easier system to learn and use. When shots are hurried and/or game starts moving, your eye goes automatically to the crosshairs, not the "300 yd dot", etc...
