You would double the clicks for 50 yards. In other words, a click at 50 yards will only move your point of impact by 1/8" vs the 1/4" change at 100 yards.

I've always found that if I 'zero' at 50, I'm a bit high at 100 yards. I shoot some of the flatter-shooting calibers. I imagine this is due to height of the scope above the rifle. Thus I prefer about an inch low at 50, then I work on grouping at 100yds (this is where I evaluate ammo / reloads) and finally, a good zero session at the rifle's intended zero-yardage.

thanks guys,
I just want to come close at 50 yards and than move to 100 yards and have it there 1-2" high so I am good for any range from 50-200 yards |

Usually the MFG will publish velocity for a load somewhere. Take that and the BC / SD values from the manufacturer of the bullet to calculate your bullet drop. You can do this either with MFG table / published data OR you can use one of many online programs to do this.

Go to the Remington website and download Remington Shoot,it will give you very good basics of bullet impact at various ranges. Have used it for several cal. for several yrs., if they still have it on there. Its very simple to use and covers just about every american cartridge, also euro cals.

Use this. Change values to get what you need.

16 clicks
That oughta get you over 2" at 50 yds. But......if I wanted a 200 yd zero, I'd sure try and shoot at 200.
That said, I don't have access to a 200 yd range w/ a bench. My std drill is to zero all my full size deer rifle ctgs 2" high at 100. That puts me a tad low at 200, but keeps the bullet closer to the line of sight at intermediate ranges. The old 3" high at 100 puts the bullet to high at midrange to suit me. |

You'll need a lot of data to be sure that where you hit at 50 is going to have you zero at 200. MV, BC, sight height, barrel length...
Calculators will get you close, but you'll just have to go out and shoot to figure it out. |

Sight in at 25yds. Check at 100yds. Finish sighting a 200. If you want it sighted in at 200yds, then move it to 200, otherwise you will be guessing. For my flat shooting stuff, I sight at 200, otherwise, I use 100.

So, your scope is calibrated to 1/4 of a minute of angle... (MOA)
At 100 yards each click will move the point of aim 1/4" (4x.25"=1")
(this is how you get the 8 clicks equals 2" at 100 yards) One minute of angle at 50 yards is equal to 1/2". That's the best way to think about it... (So to move the point of aim/impact 1" you need 8 clicks) One minute of angle at 25 yards is equal to 1/4" (to move the point of aim/impact 1" you need 16 clicks) One minute of angle at 200 yards is equal to 2" to move the point of aim/ impact 1" you need 2 clicks) it depends on the caliber of round you are firing as to how much drop, if any you might get between 50 and 200 yards... it could be close to zero, which is what I think you are thinking. |
