Last night I did some long range rimfire shooting. I was out to shoot with my newly aquired 223 tube for my Savage, and decided to give it a rest and shoot some longer 22LR stuff. Normally I shoot to 200y with my 22 rifles, especially during wind conditions to get a better experience shooting in the wind. At 600y a 30-06 or 223 still drifts less than a 22LR does at 200y, so the 22 is an invaluable training tool.
I dialed 72 MOA up (max travel left) from my 200y zero and then held over an additional 5.5 mils (3.435 moa / mil ) and hit the 400y full size torso steel (~ 18"x36" with 6x6 "head) on round 3, the elevation was a little low, and the wind was kinda nasty so the first 2 shots were definitely sighters.
To give an idea of the wind call the 223 was running 3.5 +/- moa of wind with the 55 fmj's @ 3325fps MV.
I had to use the electronic earmuffs cranked up to amplify the sound enough to hear the hits.
Once I knew where the 400y "zero" was, I held low at 200y and 300y and went 2, 3, 4 without any trouble. I was pretty happy about that.
Interestingly, to hit a 4"wx12"t plate at 200y I held under by 10.5 mil from 400y, which definitely shows that the bullet is still "rising" at 200y on the way to 4, as opposed to a "falling" bullet.
Here's a poorly scaled sketch of what I'm talking about.
