When zeroing a TA31, what should aim with, the top of the donut, the center, or what. I was thinking the center of the donut since its a small 2MOA, but Im often wrong. Should I zero it at 50 yards, 25 yards, or what. Most of my shoting will be at 200 yards, but will use it for close ranges ike 10 yards, out to maybe 400 yards. I know I said I was done with questions a while ago, but want to do this right. Thanks

The donut serves as a BDC.  The top of the donut is your 100 yd (or is it meter?) aiming point, the center is 200, and the bottom is 300.  The top stadia line is 400.

So, if you do most of your shooting at 200, sight it in with the center of the donut as point of impact at that distance.  Trying to sight in the top of the donut at 100 with the target tangent to the top of the circle can be frustrating, as I found out.  The size and shape of the target used can make a lot of difference.

This sounds like a good method. Thanks for your help.
