Thank you very much for your comments.
Centercut : it's really exiting to shoot such group, but for the fifth shot I shoot it like the other ones. The trick is that even if I know that I'll shoot only 5 shots, I conditioned my brain that I'll shoot 10 shots, in that way can I escape the stress and the rush of the fifth shot (this is the best way that I found to keep calm).
Wolfie : I don't have a coach and I don't compete.
I shoot and hunt with air guns, 22Lr and shotguns for about 33 years now. I shoot for fun, I try to improve my skills and challenge myself and this is the biggest competition for me.
I consider that shooting air rifles using pellets especially at long ranges for a combination of accuracy and precision is one or the most difficult disciplines because of different elements (pellets, barrel, weather…) and of course the shooter himself.
With the pcp technology evolution, and in order to make it more complicated, I made “my own discipline” for long range shooting; it’s a combination between hunting and precision shooting… Every time I try to get out of my “comfort zone” : I don’t sort my pellets, I don’t use bipod, sand bag, rear bag, I shoot in different weather conditions, different positions, at different distances and maximum 10 seconds between two shots… and every time I have only one goal : improve my skills, challenge the shooting conditions but the most important part in all this is to have fun and enjoy shooting air rifles.
I'm not an expert and I don’t consider myself as a great air gun shooter or a teacher, but my advice is “Save money to buy the best air rifle that you can offer, leave your comfort zone, shoot as much as you can and have fun”
Safe shooting
I was thinking the same thing. 
Nicely done!
