I have some questions regarding PCP, SCUBA tanks and cylinders.

How many shots per cylinder fill should I expect from a FWB 700?

How many cylinders can I fill with a SCUBA tank?

I don't expect answers to be that exact but just to have an idea.

It seems that I can have a good deal on a SCUBA tank.

Thanks in advance.

With Chairgun (demo version is for free), you can do some Bottle Charging analysis. If you know the volume of you bottle and of your cylinder, that is...

If I use it with the spec's from my Haemmerli AR50, it says I can get about 40 to 50 charges out of a 10 L bottle before the bottle pressure reaches about 150 bar (which is when I would normally get the bottle filled to 200 bar again). I never counted, but I'd say this is about right...

Well the problem with figuring that out is that you don't normally shoot the P70's cylinder completely empty. And every time you fill a cylinder the pressure in the SCUBA tank drops a bit.

Just for a rough estimate, We shoot 2 nights a week, precision shooters using PCP guns probably average 5 or 6 a night, they shoot about 80-100 shots (targets and sighters) a night. So lets go low and say 750 shots a week. We have 3 SCUBA tanks (we use one for the initial fill and a second to top them off) and I have to take one every other month to get filled, so I'd say we are getting about ~6,000 shots out of a SCUBA tank. But the way we are using 2 tanks may be extending our tanks life a bit.

Still a lot of shooting out of a standard 80 SCUBA Tank.

I emailed FEINWERKBAU and they said I should expect 250 shots per cylinder (I ordered two).

At an estimated 6000 shots per SCUBA tank it's definately worth having one.

Thanks for your replies.
