Traditional optics and target shooting
The Weaver Tac-3-15×50 is a serious optic. Mil-Dots are used for range estimation and are still being used and taught in military sniper training. An optic like this will help you estimate an object hundreds of yards away and depending on the operator, reaching out and touching your target with be easy with the 3-15x magnification and the wide 50mm objective lense.
Weaver rifle scopes have been around since the 1930s. I still hear people highly recommend using them on carbines or small semi-autos like the Mini 14. Weaver makes several types of rifle optics and some of them are applicable for long range shooting. Long range optics don’t have to be high magnification, but clear and accurate. With the proper scope rings, and the right kind of ammunition, your Weaver rifle scope will be capable of short and long range shooting.
