zero point for scope

Hello all.

I am in the process of setting up a f/tr rifle. I am currently trying to decide on optics and mounts, and I have a question. Let's assume I will be using a scope mounted on a 20moa base. When I center my scope (I realize it is likely to be off of the scopes center by a little but it should be close) should I center for 100 or 200 yds or should I center for a longer distance so that when shooting the longer ranges I uise less of the scopes adjustments to center on different longer distances?

Hope thi makes sence, Thanks for input.

Depends

On how much internal adjustment you have on your scope. If I put my Sightron 36X on my rifle (has a 20MOA rail) I'm 5.75" high at 100 yards with the scope bottomed out on the adjustment. So I keep that scope set for a 600 yard zero. With my 8.5X25 LRT installed I leave the rifle set with a 100 yard zero, dial up from there.
 
Your zero, short or long won't make any difference to the scope setup. Your scope has a total elevation range of X ( 40, 50, 60, or even 100 Minutes Of Angle, or Inches at 100 yards). When it is centered you will have half of the total for elevation adjustments. Even a flat shooting cartridge needs almost 30 MOA to reach 1,000 yards, so many scopes with a flat scope mount don't have enough adjustment to match the bullet drop at that distance. An inclined base will add more MOA to reach farther.
 
Hope this helps

I shoot several rifles chambered in different cartridges out to 500 meters.

I try and have my scope bases made so when the crosshairs are centered the rifle is on at 400 meters. Why...........because in most cases the total come ups from 200 to 400 are about the same value as from 400 to 500.

BTW the bases should be machined while on the action. As an example gunsmith Mike Bryant is set up to do this type of work.
