Am I too old?

No, you aren't too old Chameleon. Decide what venue you want to shoot whether it's Bullseye or any of the International sports. Find a mentor or coach at your club, or get an online coach and let them know what you want.
I'm 72 and started Bullseye about 9 yrs. ago and air pistol about 5yrs ago. I'm too old to seek the big stands, but have oodles of fun trying to get improvement, I find it very rewarding to shoot and compete in matches.

I'm 79 and took up target pistol two years ago. Yes, I'm useless but getting better the more I shoot, in fact i do better than quite a few who are much younger than me - but even more useless than me!
More importantly I love it! You've 56 years on me so go for it!

Buddy, I started at 38. My first air pistol match at 39 and I shot a 548.

I wish I started at your age. Who knows how much I could have improved over 17 years?

Best time to start was yesterday. The long you wait, the question will turn from “am I to old,” to “what if I started” when you are no longer able or capable.
