I bought a Carl Gustaf rifle complete with a Redfield scope probably from the 70s,it has two parallel horizontal lines above the cross hairs, is anybody familiar with this scope and if so do they know what purpose these lines serve. Thanks
 
One hundred, two hundred yard intersections?
Try them out.
Zero the center X hair at a hundred and see where your
shot placement is at 200 with the next line up?
Or try the 50 to 100 yard targets.
Those old Redfields were a decent scope.
I have a 2-7 on my old Marlin and do enjoy the optics.
 
I think on some of the bushnell DOA scopes the lines are to guage distance, i think it was that you compare the length of the different lines to something that is 24" wide to guess the distance it is away, kind of like mil dot for dummies
 
Google is handy sometimes, this scope has accutrac you zero the scope at 200 yards and then you use the 2 lines to bracket a deer using the zoom, then you read the yardage in the lower right and set the yardage on the elevation knob, supposed to allow for no holdover out to 600 yards.
 
the 2 lines at the top of the scope are made to be calibrated for a deer , from the top of bis back to the bottom of the chest .
i beleive it is suposed to be 16 inches

so if you come across a deer sized animal at a unknown distance , you adjust the magnification till his body fits between the 2 lines , then you have a rough estimate on the distance .

some of them have special numbered turrets for the elevation knob for different rounds .

what i did with my stw was i zero'd it to 100 yards , marked the elevation knob , zero'd it to 200 , marked the knob , same for 300 , 400 and 500 yards .

so i would use the 2 lines on the top of the scope , figure out the range , then adjust the elevation knob to the coresponding mark for that range , then fire directly into the animals body without holding over .

fool proof .... not even close ............. if set up properly by someone who understands how it is suposed to work , it is at best a secondary piece of information to help the shooter determine the range of the animal .

but i do love the older redfield widefield scopes .
