compressed air on x7

with a 3000psi tank thats normal, i got a 45/3000 tank and i get about 450 shots out of it (give or take).

It does vary.

size @ psi = shots per tank

45ci @ 3000 = 500
72ci @ 3000 = 800
45ci @ 4500 = 800
68ci @ 4500 = 1100
88ci @ 4500 = 1300

you can compare these sizes to your average CO2 tanks:

9 oz = 400
12 oz = 700
16 oz = 1000
20 oz = 1300

Those are just the specs that most manufacturers give on their tanks. Either way, you still get more shots with a bigger tank, and that's the important thing.

if you want to, save up for a bigger hpa (air) tank. a 68/4500, hpa is cheaper to fill up and the weather dosent effect your bottle, co2 dosent like the cold (you get less shots when the tank is really cold, hpa you can play in a blizzard (thats if your paint dosent freeze).

the only downside to hpa, is that the tanks are kinda expansive, but it's worh it in the long run.
