Target shooting, I couldn't hurt anything bigger than a fly but paper targets don't breath!
Tbh due to Finland's strict gun laws I haven't been able to practice with long guns in years. The nearest rifle range for me would be ~60miles away and to get a license I'd have to go there regularly for around 1 year, shoot with rented (expensive) equipment, have all my progress written to a shooting diary by the range inspector and then with luck the police maybe would give me a license to buy own rifle. Acquiring own handgun here is even harder nowadays due to unfortunate school shootings we too have suffered. However some indoor firing ranges here offer handgun shooting with rented weapons in fair price and I've visited them a couple of times.
And of course tried a variety of firearms while serving in military. I had Kalashnikov variant (RK-95, 7.62, folding stock) as my service weapon. Also got trained to use Sako TRG42 .338 sniper rifle briefly and fired a couple of belts from PKM as well.
Maybe if the gun laws here ever get loosened I'll get into rifle ranges again.
