Hey all.
This question has probably been asked inumerable times but I must ask it once more. Does anybody out there have access to the information that goes with this old redfield widefield 3-9 bullet drop scope? I have several knobs for it and each knob, to my understanding, is dedicated to a particular caliber. Any information would be greatly appreciated.
Thanks.

  If you don't get specifics - here is the deal -- Dedication to a caliber makes it easy for the user but the truth is each one has the drop for a particular ballistic coefficient and velocity - the caliber doesn't matter. You can figure out what you have by mounting them and figuring out how much drop is between each 100 yds. Then do a little work with ballistic tables or a software program -- you will find each one matches closly many combinations of bullets and calibers. For example - as a practical matter - there isn't a lot of difference in drop for most of the modern bottleneck hunting cartridges. In general terms - if you have drop compensators for the classes of 30-30, 22-250 - 30-06 you have most of what would ever be needed. With a little research you can sort it all out.

  Thanks for the reply. One of these days I'll get some software that does ballistics. I can imagine the time savings, although such things cannot substitute for actual range time. The old scope appears to have solid adjustments and really clear glass. Inside, there's what appears to be a ranging reticle at the top of the view with two stadia equating to 18 inches at a given distance according to the particular power of magnification. For example: the width of the vital area in a deer is approx. 18 in. To use the ranging aparatus, a sliding scale in increments of 50 yds., beginning at 200 and ending at 600, indicates the range of the animal by fitting the vital area between the two stadia. Then dial the indicated distance using the elevation knob corresponding to, as you say, muzzle velocity of your bullet/caliber. I am not unfamiliar with the scope, I had just hoped to get a copy of that little piece of paper telling me which knob is which.
