Rifle Scopes Sighting Distance.

[txrpls]

I have always wondered about this and I know it probably doesn't make a hill of beans, but are there any specs. of where the measurement are made for sighting in? Is the distance measured from the end of the muzzle or or the recticle on the scope. Forgive me for being anal, but I am a land surveyor and precise measurements are my forte. Just curious.

I think most would say at the end of the muzzle.

It also seems to me the sighting distance would be from the muzzle since that where the terminal balistices begin.

Since you are a PLS, I understand.

Ballistics are based on muzzle (i.e. muzzle velocity).

Reticle tracking - from reticle (relative position inside the optic) to target.

It will be more important ballistically that you pull your 300ft tape to the proper tension when you measure the distance, be it from your muzzle or erector

Don't mind me, I'm just a lowly grading foreman/gradechecker and am used to correcting surveyors' "precision" in the field......

Try it both ways and let me know how many mils you were off.
