One more thing to add is the fact that unless the scope was designed for that caliber of rifle, it's accuracy will be affected - by it's adjustments.

From what I remember, most rifle scopes of that design - unless supplied with different adjustment knobs = are really designed for a 30/06 type of rifles ballistic's.

If you have a rifle that has less bullet drop, you really cannot go by what the manufacturer claims for adjustment by range.

What you will find out is that if you want to know where it is going to hit, you are going to have to spend time at the range and shoot it until you can develope a score card that will give you an estimate of how much to adjust it to get it to hit where you want it to.

Basically the same thing that snipers and the military does with their scopes.
