Let us make the following survey:
Percentage of time or quantity of shots per year (i.e. 2005) in each discipline (training + match)
Air Rifle 40% 3500 shots
Smallbore
Prone 30% 2500
Standing 20% 1000
Kneeling 10% 500
Lera:
You posted "I'm 16.5 first shoot when I was 6.5 years old."
If you shoot 1.000.000 on air discipline in 10 years then you have made 274 shoots every day.
That seems a little "too much".
Cheers
