A buddy bottle is a small bottle for use on an air rifle, like a Rapid, Super 10, R10, what you are after is one of these....

Hi, I have an AA S200 which gives me 60 -70 shots on a full tank, No problem at home I just refill from my divers bottle, but i want a smaller lighter bottle to carry around with me. I have heard of buddy bottles and I assume thats what they do, any one any ideas where I can get a bottle and whatever i need to fill the gun from it and to fill the bottle from my big dive bottle?

Yes you can couple it (ooh er missus, connect it?) to your dive cylinder, open the valve on the small cylinder first, then on your dive cylinder, fill to 250 bar, then shut off, have a tea, a read of the forum, check pressure on the small bottle then top up again to 250 bar, close both cylinders off, bleed the air line and uncouple...
would've thought a 3lt 300 bar tank would be a better choice
Bestfittings were doing a carbon fibre bottle 1 litre. That would be great.
The problem is that at 250 bar you may not get that may fills with it.
250 bar at 500cc is 125,000cc at 1 bar
S200 cylinder is around 150cc and fill to 190 bar, shoot down to say 130 bar? 150cc at +60 bar needed to top up, 9000 cc at 1 bar.
But you only have 500cc at 60 bar difference before the buddy bottle is down to 190 bar itself, which is 30000 cc at 1 bar. So doing the maths, you'll get about 3 fills before you're down to 190 bar in the buddy bottle, depending on whip length. You'll get maybe 1-2 fills below that, but they'll drop down below 190 bar quick.
Depends on how long you're out for and how much ease you want, and carry weight. If it's in the back of a car and a short walk, or you're shooting from a fixed position where you can take a small bottle then a 3L 300 bar bottle will give you a lot more fills for probably only £20 more and it only weighs around 4kg if you get a stumpy one and around 5-6 if you get a long one.
A 3L 300 bar bottle will give you about 330,000cc at 1 bar overhead, meaning you'll get about 30 fills before dropping down below 190 bar.
I've got a stumpy 3L I can weigh if you're interested.
If you're walking around and carrying the buddy bottle then it may pay to go for a 500cc, but you're paying a lot for that luxury.

all depends how far you wander from your car I suppose but with the amount of shots you get from a s200 if your shooting rabbits you would have to possibly return to the motor as you'd struggle to carry them all if you hit every shot
when you returned you could top up
