Dear Carl,
I have the same problem and have not been successful finding an actual manual. However, if you go to "abousainc.com" there is a link for general instructions. It is under "Redfield Scopes" and then scroll down to "How to use the AccuTrac." However, it does not give the starting point of the instructions and only gives the table for the different dials. I will try to explain what those 2 lines at the top of the reticle are for.
The average whitetail from the top of the shoulder to the bottom of the chest should fit exactly inbetween these 2 lines when the zoom is used correctly. If you notice, the yardage counter in the bottom left (4:00 position) it will tell the yardage of the deer when you zoom in or out and the torso fills these 2 lines. You may also notice it starts at 200yds. Thats because you need have your rifle zeroed in at 100 yds. So there's no point displaying less than 200 yds. This is where the different dials come in. For example: the deer is 300yds away. You zoom in or out until the torso of the deer is inbetween the 2 lines then look at the yardage in the 4:00 position. It should read approx 300yds. Then you dial up to the number 3 position on the elevation knob and aim as you would if the deer where at 100ds.
Look up which dial you need on the ABOUSA site on the AccuTrac tables I mentioned earlier. You might be lucky and find the dial you have is the right one for your caliber. If not, this company was once the offical repair facility for Redfield, Colorado. They also have the different dials for sale but are quite expensive...$10--$30 each.
Hope this helps,
Mark
One correction to the above. I said the rifle needs to be zero in at 100yds. That is incorrect. It needs to be zeroed in at 200yds. and that is why there is no point displaying less than 200 yds in the vewer inside the scope at the 4:00 position. In other words if the rifle is zeroed at 200yds, most calibers will most likely group approx 2.5 inches high at 100yds and be dead on at 200yds. If the deer is 300 or 400yds then you would dial in for those numbers and the dial automatically adjusts recticle elevation for your particular caliber and bullet drop. The tables I refered to earlier are based on standard factory loads,Caliber, bullet wgt, and muzzle velocity. If you reload much hotter or lighter rounds, of course this would be off. So at the very bottom of the Tables there is another Table base strictly on ballistic tragectory not found in the tables above. However, know you would have to know the ballistic information on your paricular reloads ie. muzzle velocity and tragectory.
Hope this helps,
Mark
