How many here use a Mill Dot Recticle in your scope to judge range? I really don't have the extra cash to buy a range finder so I bought a scope last week with Mill Dots to judge range. I bought a Vortex Viper 6.5x20x44 scope. I will some day when I can afford it buy a Bushnell arch 1200 but until then I am going to have to make due with this system. The math really is not all that hard. If you know the height of your target in inches you would multiply that times 27.77. Then devide that by the number of Mills read. I am going to buy one of those Milldot Masters next week to help me with this so I don't have to carry a caculator in the field. For those that don't know what that is it is a slide rule type thing. It greatly speeds up the process because them Groundhogs are not going to hang around all day waiting for you to come up with a shooting solution. Of those that respond here about using a Mill Dot system for judging range I would also like to know if you use the Milldot Master. I made up a drop chart today for my 22-250 that I can tape to the side of my stock. I also went to the range today and everything checks out to the 300 yard mark. My drop chart goes out to 600 yards so I would bet it won't be exact out that far but I bet it gets me a lot closer than just trying to guess hold over. When I say I made up a drop chart what I did was run my info through a exterior ballistics program. You tell it what your zero is, caliber, Balistic coeficent, well hell it is just easier to give you this link and it is a good one to save to your favorites.

This program gives you how many clicks up you need to go for the range you are shooting at. The thing is that Groundhog is going to die of old age if you have to count every click. I figure mine in MOA. For example I am shooting Winchester USA ammo that is 45 grain bullet at a MV of 4,000 FPS. I run it through that program and with a 200 yard zero at 575 yards with my scope that has 1/4" addjustments it says I have to come up 47 clicks. My scope is devided by MOA 4 clicks = 1 MOA at 100 yards. Well When I made up my drop chart I did not write down 47 clicks up because that would take all day counting clicks. I devided 47 by 4 and it comes out to 11.75 witch =11.3 clicks. So all I have to do is dial in 11 minutes and 3 clicks. I hope you guys follow this for those that are new to this like I am. I know it can be hard to understand. I am just trying to put it as simple as I can. So I have rambled enough and this is my system so far and I am only a few into this. So this is a learning thing for me also. If any of you guys that have more experince than me see any mistakes in anything I have written please correct me because I do not want to learn it the wrong way. Take Care Dale
