Before we jump further down the wormhole into other hobbies unrelated to pinball, beer, etc...the amount of technology in airguns has been nothing but stunning in the last few years...
As an avid marksman in both combustion propulsion and compressed gas propulsion, the newest PCP's are crazy awesome! Legitimate .22lr power and accuracy, without the report (depending on how you adjust for velocity, as you can still get a sonic "crack" above 1100 or so fps...), and have become shockingly affordable.
Hell, nowadays, for about $500, you can get a Marauder, a cheap tank setup (so you don't have to hand pump), a semi-decent scope, and you can be shooting sub moa out to about 75 yards all day on a single gas charge. Spend a little more, and you can have a world class accurate setup, or a larger caliber, that you could technically hunt game with. A large grain .30 projectile at 1100 fps out of an airgun is still a large grain .30 projectile at 1100 fps...
And since these aren't firearms, you can have them shipped to your door, and you can even fool around with making/fitting a homemade suppressor, only for lawful purposes, of course.
Now back to your regularly scheduled beer talk on a pinball forum
