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

I may have it completely wrong, however my understanding of BDC reticles is the the hash marks loosely correspond to 100, 200, 300, 400 with a 100 yard zero etc if using normal loads and bullet weights and using a cartridge compatible with the particular reticle.

It's unlikely they will line up exactly but they do get surprisingly close if you look at the moa numbers.
Not as precise as dialing but better than estimating/guestimating hold over.

I've tried it out to 400yards and was way closer than I expected.
