Here is the Situation . 300RUM with Leupold scope hitting less than 1MOA at 200 yards. Sighted in a 10 power. I have ballistic charts for up to 1000 yards.
Here is the question:
If you sight in at 10 power and in a hunting situation say 700 yards you increase the magnification to say 20 will that throw off the internal mechanics of the scope and blow the shot
