The important number is how much elevation you have left after you zero the rifle. If you zero at 200yds and have 20moa left, you are good to go with the 7mm RM (for big game hunting).

I was probably going to zero at 100 only because the range that I go to only goes to 100, if I sighted correctly at 25-30 yds theoretically where would i be at 100

With the 140TSX, you'll probably be able to get around 3200fps. Sighted in at 100yds, 18moa will get you to 800 (depending on elevation).

Sighted in at 25yds will put you 3" low at 100yds.

Re: Possible POSITIVE error on my Nikon 4-16x50

I believe my elevation is 685ft. If I was a little further say 30-35yds where would i be at 100? Would I be higher or lower? This is my first manual boresight so I am trying to learn a few thing as I go

Just try to get it 1" high at 25yds and you should be on a large target at 100yds.

All you are trying to do with bore sighting is get onto the backstop so you know how much and which way to adjust the scope.

Ah that explains it huge difference between clicks and MOA. That being the case I would say you should be good to go with that much "up" adjustment left. Good luck with your project.
