Set a 1/4" KYL rack at 50,let them cypher DOPE from a 50yd zero and watch The MAGIC happen in real time. Once a "clean" is realized,simply stretch it farther. It's instant visual feedback and instant audible feedback,that will illustrate with unerring cause/effect,what do what and more importantly WHY. It can go no other way. Hint.

If only for starters. Hint.................
