I have been shooting my entire life. As a sprout, I set up a range in the longest aisle of the barn, bullet trap and all. Maybe 5000 rounds of .22LR later, I had figured out the basics of trigger control and open sights. Both pistol and rifle. One round at a time.
I know it was 5000 because dad was cheesed I'd burned through an entire case of .22 in only a couple months.
Now, decidedly far from being a sprout, I find bifocals and pistol shooting to be problematic. I can still hit what I want, usually in decent time, but it's getting harder. A lot harder.
Time to bow before fate, and embrace new tech while I'm at it.
Of course, now I need a few cases of pistol fodder.... just exactly when the politically driven ammo buying is at it's height.
Oh well..... more than one way to build muscle memory.
