>So, with a handgun, I'm supposed to hit a 1cm dot at 25m?
Well not the dot but the 4in circle.

Arguably it's way less fun on your own than with some friens. But the real fun starts when you can shoot at your own targets outdoor. Fruit, bottles, cars, pics of Greter. But such opportunities are rare. More reasonable is shooting at moving targets or moving through a stage in dynamic shooting. But for this or tactical shooting you gotta be proficient at the basics first even if they are boring.

That wears off quickly. I feel nothing even while running through a stage in IPSC. It's like anyy other activity. I don't rush, I'm slow but accurate.
