Gonna get a new scope for elk/mule deer. Thinking of Nikon/Leopold custom "etched" scopes based on ballistics I provide vs using BDC scopes. Anyone use either? Both? Compare? Like the idea of dial and shoot but is it reliable? Ease of use? Normally won't shoot over 300 yds but have seen guys take 500- 600 yds successfully on elk. Any insight, advice or experiences? Thanks.
