Having never used or even seen one of these (only read a bit about them). My understanding is that based on the type of animal you are looking at, and what power you are looking at it with, based on the different circle sizes on the recticle, you can estimate how far away the animal is. So, here are my questions: - How accurate a system is this? - How far out can you accurately estimate distance using this recticle? - What type of recticle do you like to use for LRH? Thanks everyone.
