tried the Leupold 2x handgun scope on the Python during deer season. Worthless, during early and late legal shooting times. Couldn't make out the crosshairs.................that's where the lighted reticle comes into play. Promptly, replaced that with a red dot. Irons
Even a large aperture with a light pipe front on a carbine was worthless.............and I always had excellent vision till age caught up,in my later years. Still don't need glasses all the time. Watch TV without them. Cloudy days, I'll hunt without them. Outdoors, I wear them because their transitions and don't have to switch back and forth, as I would with sunglasses.
When I hunted in Michigan, poaching was common in my area, the deer were basically nocturnal. Was hard to harvest a deer of any kind. Michigan was generous with landowner doe permits for our area. With a doe permit anything was legal. I shot may a deer that were just silhouettes, mostly with a bow. Only hunted on the weekends. Working back then. Many a year, you might only get one opportunity to see/take a deer.
