Would like to scope my M1A and was considering a mill-dot. Really tho, all I want to use the mill-dot for is for hold over and windage. Is this a dumb idea or not? How big will the dots be....too big to be of any real use at the longer distances? In other words, will they end up covering a smaller target and be more of a hindrance? Never had one in the field to look at so I don't have any clue what to expect. Thanks.  Greg

They could pose a problem for small targets at distance.  However, they are great for ranging- estimation.  Take the estimated height of your target in yards, multiply it by 1000, and divide it by the height of your target in mil dots (as seen through your scope), and presto; instant accurate range.  This will allow you to adjust your scope elevation, for the proper range, and you will be able to use your cross hair, on smaller targets for more precise shot placement.  You may also want to look at a German style reticule.  I believe they use a hash-mark system, which may allow you to do hold overs on a small target.
