A lot of good reasons were ahead of me, here's some of mine:
- ammo- cheap to shoot: 320$ a case, and cheap and easy to reload.
- easy to shoot: no recoil, little muzzle blast, so no flinching etc that screws up many shooters of larger calibres. This really shows when you take your wife/gal friend out. makes your hobby easier to do if you can share it.
- robust. Plain lasts a long time.
- accurate, good range (tough to find a 1,000 m range, plenty of 300 m)
- I REALLY like the fact that me owning one pisses of the Liberals/PC crowd.
- Comfort. The telescoping stock sold my wife, plain fits.
All boils down to fun to shoot- light, accurate, fast, no recoil, cheap.
