I have my White Oak Service rifle bottomed out at 200 yards. At 200 years I never found any environmental conditions that change the elevation. Windage yes, but not elevation.

I like to keep the sights bottomed out so I know what ever range I fire, I know I have to adjust from the bottom.

I have a habit of returning the sights (bottoming them out) when I'm finished shooting a stage. I always know I have to come up from 200, I never have to wonder if when going to 600 did I have on my 200 or 300 zero.

Just a habit I developed when I started shooting high power nearly 40 years ago.

I suppose if you are only going to shoot at 200 it doesn't matter, just remember to mark your sights so you can look down and instantly see you are at your 200 yard zero.
