Why not put a rangefinder in a scope and program it to auto adjust the reticle for whatever distance it is pointed at? I'm sure a system could be worked out 
For example, once you zero (calibrate) it at any distance (say 25 yds), it would be able to re-zero itself to any other distance. |

I think this already exists... not sure what product... but I am sure there is... Unfortunately, I bet if there is a product like that, it would be extremely expensive and would only be in the economic realm of .50 Caliber shooters... Afterall they spend thousands upon thousands for just the weapon's platform... what's a couple thousand on a good scope? |

Sounds big, delicate, and expensive. Oh hush with your naysaying! I know there are scopes with rangefinders in them but it couldn't be that hard to put some little servos and software to auto adjust the reticle in with it Heck you wouldn't even need to rotate your 'clickers'. Just overlay a digital reticle on the glass and make it move around.

Well, it isn't that simple. So you set the reticle on a distant target, then the servo moves the reticle and in doing so, the reticle moves off target which could be at a different range so now the reticle moves AGAIN to set the POI. You would be like a puppy dog chasing its tail. |

Bushnell and Zeiss make a scope with a range finder built in. Displays the range on the sight picture, I think Barret makes a uber one that calculates elevation, barometric press., etc and computes compensations. Nothing that actually adjusts the POA for you though. ETA  BORS is an integrated electronic ballistic computer that mounts directly on your riflescope and couples to the elevation knob. Just turn the elevation knob until the LCD displays the target’s range. The BORS’ three internal sensors will have automatically calculated your ballistic solution. It compensates for aiming up or down, temperature, and barometric pressure changes. It even tells you if the rifle is canted. Place the crosshair on the target and fire with first-round confidence. http://www.barrettrifles.com/home/optics_bors.aspx |

Heck, a little solar panel could be put on top of this magical scope so it doesn't need batteries! |

Say the rifle is zeroed at 300 and the target is at 500 so you put the reticle on the target, the range finder now moves the reticle DOWN. But on doing so, it now sees the reticle is on a target that is now at 250 yards so it then moves the reticle back UP. It wouldn't be simple, you would HAVE to have a solid hold on the target, then when the reticle is on the target, you press a button and it moves the reticle down (in the above situation) to the proper range and you then must raise the rifle back onto the target. |

Ah, I see what you're saying. So when the reticle moves, that means you have to move the rifle for your new point of aim but then that will probably change the range again causing the reticle to move. No matter. I'm sure some brain out there would have an idea to fix that problem. |

I'm sure some brain out there would have an idea to fix that problem. VERY simple... rather than make it COMPLETELY automatic. place a pressure switch somewhere near the trigger area, that would be engaged for when you want the rifle to "Sight in" for that range. then the rifle would adjust for that range at time of activation and stop. Then you would simply point, aim shoot with confidence. |

My EOTech uses the same exact technology as the holographic HUDs. I don't hear a hum. The scope suggested, would merely be a smarter version of the EOTech, ... with magnification, range finding capabilities, and auto adjust features. It would be bulkier, heavier for sure... but there would be no "Hummmmmm" noise. |
Sounds like you want an M-21 ballistic computer...by the way, it solves the convergence issue by moving the TUBE, instead of the reticle. I expect expense, size and delicacy is the reason rifle scopes don't have these. I am surprised there aren't more integrated LRF/scope combos out there, LRF technology is pretty mature now, and the bulk and expense seems like it'd be worth it, especially for days when your spotter called out sick

Kinda like an automatic version of the old Unertl scopes.

They've got a huge LRF with a little red-dot slaved to it?  ETA - oh, that's a 203 sight...lrf for under 500m seems to be kind of excessive for an area effect weapon. I guess for the smart rounds it's necessary, but for plain old HEDP seems like a waste. I know none of us used ours (which admittedly didn't have the red dot) because they were heavy and bulky and it's pretty easy to get proficient enough with a 203 to not need it.
By the way, the M-21 moved the GUN tube, not the optic tube, which means you just laid the reticle on the target, press the button, and the tube moved to hit the target based on range, temp, etc. Nearly idiot-proof, and fast to use. Also, hideously expensive and delicate. Of course, this is also 30 year-old technology, I imagine the CREWS is comparable in performance at a slightly lower price. |

It automatically adjusts for spectrum, range and caliber. |

I'm pretty good at estimating speed. Car manufacturers are dumb to put speedos in cars. If a skill can be learned everybody should know how to do it all the time. |

I have seen the data of the new Laserscope from Burris- which does exactly that- the aiming point will move up or down the veritcal crosshair- to adjust for range and ballistics. It will be awesome- if it works as planned. I plan to test out the first one I get. Dave |
This baby had exactly what you're describing way back in 1950, and it could also compute lead on a moving target. It was the Sperry A-1C radar gunsight, and it was a BIG advantage over MiG Alley. The XM25 has pretty much what you're looking for, plus it links range data to the projectile before it shoots, telling it when to go *kaboom*.  You can have one for your rifle, too. How much you lookin' to spend? This one doesn't have all the features you want, and it's $12,000ish Zeiss Hensoldt 6-24x72 SAM   ETA:  |
