Re: anyone have a bushnell 6500 4.5-30x50 on an AR?
The SFP scope can only be used (easily) for mil dot ranging at one magnification. On this scope it's 10X. The + is that the reticle always appears the same size relative to the viewer.
The FFP scope can be used to "mil" at all magnifications. The reticle appears to the viewer to get larger as power is raised.
In reality, it stays exactly the same size relative to the target.
Actually, IMO, the whole mil dot thing is another symptom of "tacticalitis". Very few real world tactical or hunting shots are taken beyond the point blank range of modern cartridges.
As the old master Jack O'Connor put it in his "rule of three".
Sight in your modern rifle 3" high at 100 yards and you can take any big game animal or man out to 300 yards or more.
In spite of the BS put out in the gun rags, western game & fish departments statistics prove that most Elk are taken within 150 yards. Antelope & Deer 200.
I happen to like the Schmidt & Bender #8 Varmint reticle far better than mil-dots as it is a FFP design, nowhere near as "busy" as mil-dots and once you learn where the bullet lands relative to the range it is KISS. Not a scope 4-16x50, for deep woods but perfect for Antelope & Mulies.
