About 5~6 hot shotsa fill using Eun Jincandrop a bigtank into 'refill zone' within a tin of pellets or less.
`
For FT or match guns 3000psi should do just great. For 100yd+ hunting applications, my personal preference is a Sumatra, Career or DAQ with a field tested trajectory dope sheet.
`
For a twisted up long Sumatra at full power from a3200psi fill 5~6 shots &refill the 390cc reservoir@ 1200psi is only 14 fillswith an 88cu.ft. 4500psi tank so the air efficiency isn't quite the same as a ~19ftlb FT rifle, butFT rifles are a bit different to hunt with at 100yd+ thanthe Korean cannons are.
