RE: We speak of long range in here so.....
I was a hunting guide for quite a few years. As I stated on another post, not one hunter out of ten can hit a deer at 300 yards with any consistancy. A deer is a pretty small target at 300 yards and very little error in range estimating or the slightest wiggle will cause a miss by yards at that range. Most hunters can connect at 200 yards most of the time on a still target with a good rest. I would be suprised much more if the average hunter could hit a deer at 300 yards than if they couldn't. This is just the plain hard fact.
