Ok so I purchased a bushnell 3.5x21x50 and I went with this scope cause I like the h59 reticle but I have a few questions I just can't seem to find. What range do I need to zero the scope? To be able to use the mils correctly? Iam shooting a dpms lr-308 24in barrel and my handloads are 168gr Smks with 43.5gr of imr4064 velocity is around 2672fps. Iam completely clueless on this reticle I've never shot with one before. All help is greatly appriciated, thanks in advance.
