Thread: How do I set up and use a BRH (or BDC style) reticle?

It's a bit goofy but it's a useful illustration.

When you're looking at a deer at 400y (360m), it will look something like this (aiming point 3mil down).

Your crossbars are 1mil spacing, same as the dots in this reticle.

Note at 400y you have a pretty large vertical margin for error so it doesn't matter too much if your 400y zero is actually 3.2 mil down.
