In my home state where I grew up --running shots on whitetail were how we grew up..we would do drives through harvested corn fields or shelter belts of trees with posters at the end --90% of all deer I took prior to moving to Montana 25 years ago were running...my point in this is I feel its a huge advantage to have grown up that way and start doing it as a kid..and continuing to do so through most of your life..also, all of our rifles we all open sighted as our family was too poor to buy scopes which also I feel helped.

We used to practice by putting a square cardboard target inside a used a car tire..step back about 100 yards or so and have a friend roll the tire down the hill..so how many times you hit it from a fully loaded rifle..seemed like that and practicing on running jackrabbits in the rest of the year always kept you kinda sharp...

Also feel if you think of everything you need to do when it occurs you will be behind the 8 ball..it has to happen naturally. Muscle memory --so practice practice practice..

I find it really no different than most things in life such. In martial arts, if you get attached and have to think of what you need to do, your gonna lose..but, if you respond quickly and accurately from lots of practice and training, the odds are in your favor..

Just my thoughts on this ..
thx
