I've noticed that there are a lot of HFT shooters on this forum that are keen on the Hawke SR6 reticle, and I was wondering what its benefits were? The SR6, like Hawke's Map 6a reticle, appears to have irregularly spaced elevation markers, and I have often wondered how suitable these reticles are for range finding via the bracketing technique. According to Hawke's website the Map 6a reticle features "Hollow bars are calibrated for 3, 6 and 9" bracketingwhen set on 6x magnification" but it doesn't tell you at which distance this is true. Also, on the SR6 reticle, there are a number of lines etched in the bottom left hand quadrant of the reticle â€“ what are these used for? Cheers, Cam.
