villaman 9,979 Posted May 5, 2018 Report Share Posted May 5, 2018 vT = Tank Volume pT = Tank Pressure vB = Buddy Bottle Volume pB = Buddy Bottle Pressure Number of fills = (pT - pB) * vT / (pB * vB) 2 Quote Link to post

Same here mate - I've got a head ache just looking at that lot I'd go with: 12 ltr cylinder ÷ HW100kt = a fair few fills Honestly, feck knows but, a full 12 ltr cylinder will last you a while.

j j m 6,478 Posted May 5, 2018 Report Share Posted May 5, 2018 i had one for my rapid 7 it lasted 2 years before it needed filled Quote Link to post
Deker 3,450 Posted May 5, 2018 Report Share Posted May 5, 2018 I run a 232 12L for my FAC Falcon, it does for me but there are times a higher pressure smaller bottle seems better. For a normal 12 ft lb rifle a 232 12L will be more than adequate for most people, but if you are a high user you may want to consider something else! Quote Link to post

Jonnyb6161 80 Posted May 5, 2018 Report Share Posted May 5, 2018 Be aware of the age of the bottle. You'll have trouble getting it filled over 15 years. Probably wise to get it inspected. 1 Quote Link to post

Jonnyb6161 80 Posted May 6, 2018 Report Share Posted May 6, 2018 Personally, I wouldn't buy a second hand bottle without an inspection/ test. Also, unless it's insanely cheap (btw that would also raise a few worries) I wouldn't buy a bottle older than 5 years old. Another thing, is the reason you're talking about a 12l bottle that that's what is available. A more modern 7l/300bar bottle wouldn't be much different in terms of number of fills but be smaller and lighter. That aside, I would be extremely careful about buying used without testing irrespective of whether it's in date or not. Please be careful and good luck. 1 Quote Link to post
