Hello guys I am new to long range shooting. I am trying to get set up to shoot ground hogs at possible 600yds. I bought a TC Prohunter in 25-06 and put a Nikon monarch 6.5x20 ao with target knobs. It is 1/8 click at 100yds. My problem is I can’t figure out what my clicks will be at 300, 400, 500, 600yards A friend that got me into this has the same scope and gave me fraction values that ended up with a 1” click at 500yds. I can’t make this work in my head???? I took my rangefinder to a nearby gas line and shot my new gun at 200ysd. And reset my target knobs to “0” then shot at 300 and 400 and 500. my results were 13 clicks at 300yds 21 clicks at 400yds 44 clicks at 500yds Not sure of my 500yds distance but it is close. I had to shoot it from my 400yd target? What I want to do is fill in the gaps enough to get me close so I can go hog hunting. But I cant seem to get the math to work??? Any help would be appreciated.

I am shooting 100g Nosler BT my crono says 3500fps give or take I am thinking that my 1/8 click would double every 100yds?? thanks for the help

What alltitude? Also is your scope adjusting in 1/8' per hundered yards or 1/8 MOA it makes a difference.........

Not sure of altitude 1500 to 2000?? The scope specifications say, adjustment graduations= 1/8:1click 1/8:1 DIV I just thought that was 1/8" at 100 yards?? I guess I have a lot to learn. Thanks Pa Roger

At each range, the "Click" value is 0.125" times the range divided by 100. This is a fancy way to say at: 100 yds, each 1/8th click is worth 0.125" (1/8th") 200 yds, each 1/8th click is worth 0..25" (1/4th") 300 yds, each 1/8th click is worth 0.375" (3/8th") 400 yds, each 1/8th click is worth 0.500" (1/2") 500 yds, each 1/8th click is worth 0.625" (5/8th") 600 yds, each 1/8th click is worth 0.750" (3/4th") 700 yds, each 1/8th click is worth 0.875" (7/8th") 800 yds, each 1/8th click is worth 1.000" (8/8ths"). While some purists will whine about whether the clicks are equal to 1 inch or 1 MOA... the difference is so moot that it is a waste of time to dwell on it, but here it is anyway. An moa is equal to 1.047" at 100 yds, so at 200 yds it is 2.094, etc. But it is moot because very few scopes are exactly 1" or 1 moa, so if you want to be that anal, you will have to check the scope out yourself, a very hard job for the non-optical en-ga-neer to do. Now to your shooting chart. This should give you a start in woodchucks. 0 clicks at 200yds 250 yds = 6 clicks 300 yds = 13 clicks 350 yds = 21 clicks 400 yds = 29 clicks 450 yds = 37 clicks 500 yds = 44 clicks 550 yds = 57 clicks 600 yds = 68 clicks Enjoy... .

Thanks for all your help!! I am not sure why 400 yds did not work. 500yds is the one I was not sure off?? Again thanks for all your help. Pa Roger /ubbthreads/images/graemlins/smile.gif

I know it's been a long time since this thread was active, but I'm going to put in my $.02 anyways. Ok, first of all, if you are going to be shooting long range you need to learn MOA's. For ease of argument. 1 MOA = 1" at 100 yards 2 MOA = 2" at 100 yards 3 MOA = 3" at 100 yards, etc. 1 MOA = 2" at 200 yards. 1 MOA = 3" at 300 yards. 1 MOA = 4" at 400 yards, etc. There is no such thing as a 1/8 click, a click is not a unit of measure, therefore you cant divide clicks into eights. Your scope is 1/8 inch at 100 yards, or let's just say, 1/8 MOA. Your scope should have full numbers printed on the turrets with 8 clicks between full numbers, the numbers mean MOA's (not exactly, but close enough), so if you need to dial 6.5 MOA, just turn the knob to half way between the number 6 and the number 7. (go to number 6 and then 4 more clicks) So: 13 clicks at 300yds ==> 13/8 = 1.625 MOA, or 1MOA and 5 clicks = 1 click past 1.5 MOA (1.625 X 3 = 4.87" drop) 21 clicks at 400yds ==> 2MOA 5 clicks = 1 click past 2.5 MOA (2.625 X 4 = 10.5" drop) 44 clicks at 500yds ==> 5.5 MOA (5.5 X 5 = 27.5" drop) All I'm saying is that if you use clicks you will get lost really easy and it takes forever to dial in a shot, plus if you move to another scope that has 1/4" MOA clicks you will be lost because you will need half as many clicks with the new scope, but if you learn MOA's then if you are used to dialing 5.5 MOA in one scope, that's all you have to do in the other scope. -X3M
