Trying to get things in perspective, and really it’s about frequency of fills which is down to frequency of squeezing the trigger. I use my guns most 4 to 5 times a week ,hunting, practice at home, and the occasional range day. ( av 20 pellets / session)
my last bottle fill was Jan this year, 7ltr bottle = £7, that was 290 bar, in that time I have had 35 gun top ups ( average bottle size 200, going from 150 to 220 bar) Currently my bottle is running at 220 bar,
so, I reckon a 7ltr bottle will last me about 8 months ? Which is a less than £1/ month ( ignoring purchase price, testing, travel to fill etc)
can’t really justify a decent pump, would probs take over 10 years to pay for its self.
