You guys must be blind as bats. I still hunt irons on my Win. 30-30's and mt T/C Hawken every season and I can and do still kill deer with them in dark hemlock forest early and late right to the limits of legal hunting hours. Granted you do need highly visible irons, which is why mine all wear fiber optics these days but I do think this "have to have great optics" shyt is just an excuse to not practice or even try irons by many hunters today. Also, for chrissakes the way many talk you'd think the only time you can kill deer is before sunrise or after sunset. Sheesh.
