The differences I have seen in real life were within the 1" number I stated but there were many other outside influences such as shaft diameter, etc.......

My main point still stands........there is no usable advantage in the deer hunting woods for this kind of speed unless your not using a rangefinder past 30 yards, in which case you really should be. I'm pretty good at judging distance and have the hardware on the wall to prove it, but still pull out the rangefinder every time I'm looking at an animal past 30 yards that's not made of foam. If I don't have the time to click the rangefinder, I don't shoot.

There is nothing wrong to like the speed and think it's cool, I do as well........but there is no way I am going to believe it's putting more deer inanyones freezer. [8D]
