Scope Measurement Calculation

Was wondering if this would work and give me an accurate Scope Height measurement to enter in my Ballistics program.

From bottom of my base (where base contacts top of reciever) of my mount to the Center line of my scope is 1.062"

The Barrel on my gun at its largest point where it mates up even to reciever is
1.175"

I divided 1.175" by 2= .587" to get centerline of bore. I then added this to my other measurement of 1.062"

I get a height of 1.649" from Centerline of bore to Center line of scope.

Is this the correct/best method to get this measurement?

Thanks for the help.

Dee

The blue colored part of your post up above is where it will let it work or not. If it's flash it will work good if it's not it won't; of course you know that. Aside from that, it sounds good to me!

Re: Scope Measurement Calculation

The way I figure is...

Measure the OD of the edge of the bell of the scope at the objective end, then measure the OD of the barrel directly beneath the bell of the scope, add then and dived by 2... then measure the distance fron the top of the barrel to the bottom of the bell of the scope and add that to the previous number, that is the correct distance from center of bore to line of sight.

If you have a tapered base(s) you should compensate for that depending on how accurate you want to be.

That, also works!! Both ways should give you more than accurate results.
