Difficulty is a state of mind - very Zen
And of course your right.
I love the stuff where i can see people coming to a target and you can see it in the eyes......it is like they have a flashing blue light on thier heads
I am still amazed at how many dont do really simple things like watch the top shooters and see how they take shots, looking a face plates for patterns that tell you so much like wrong range estimation ofr wind effect and the simplest of them all, looking down the side of the barrel to see if the window is clear.
Practice tuff stuff and you will begin to improve the ratio and your confidence will improve.
Suddenly shots that spook become bread and butter.
Start close, get tough and then push the range till it tests, go tough again and push when the improvement shows through.
Most of the battle is in the brain
