You don’t neeed to got to a shooting range to shoot air guns.
If you know of any people who live outside the city of Tacoma. With a little bit of property you can shoot in the yard.
20 yards is sufficient. Just remember to treat that air gun like a real gun. Pellets will go through fence boards. So you need a good backstop.
Or go find some public land and a bit of privacy. Bring a shooting bench or some sort of tripod.
I shoot out my living room window
I made a cradle that mounts to a camera tripod so that’s what I use for a rest. This is not the best photo but you’ll get the concept.
