Hand pump questions

[C.V]

When I used a pump it was about 6 strokes to pressurise the hose up to match the rifle and then roughly 10 strokes for every 6 pellets fired with a .22, or 2 strokes per pellet fired in .177.

I did once pump a stealth bottle from 120bar, never again - top up every 20-30 pellets.

I have looked at the Stealth and it has a 490 bottle, which is lots more than a 280 rapid bottle.
Was your bottle the standard 490 Mr Bear?

There must be some maniac on here who has filled a 280 bottle with a pump????

Is it the number of pumps that is an issue or is it that it become harder to pump once the pressure gets up? Or both?

I used to have a hills mk3 pump and found it easy enough to fill my s200 and super10 that I had at the time I did the s200 in one go and the super10 in 2 bit I am fairly strong and was at the gym a lot at the time so maybe wouldn't fair aswell now lol.

On another note my mate had a Webley pump and it was shite compared to my hills.

Yes it was the standard bottle.

It's a mix of both the pressure & the volume,
as the pressure increases it gets a lot harder to pump & the more volume you need to fill obviously the more strokes are required, which is why I go by strokes per pellet.
bottle size is irrelevant if you top up after X number of shots, most manufacturers also say to rest the pump for 5min every 50 odd strokes.

It can be quite a work out using a pump, depending on your height/build & the height/stroke length of the pump,
for some people it's just on their arms which is a similar effort per stroke to a press-up,
For taller people they might need a bit of a squat or abdominal bend to get the handle right down.

Personally I would not like to fill a bottle gun with a pump. Guns with small cylinders ie AA S200/400K, BSA Ultra etc are pretty easy.

Completely agree. I fill my scorpion with my pump, although it's mostly topping up. Have filled my hw100 from near empty with my pump before but again, it's a small cylinder. I normally pump 50 bar, bleed and leave a few minutes. This prevents heat build up.
Effort is easy for topping up and doesn't take long.
I've never had a problem with moisture. Always pump indoors and have inspected the inside of my hw100 cylinder. No signs of moisture whatsoever. I use an RWS Pump which has a moisture filter fitted which I inspect every now and then.
Filling a bottle gun would be an effort however and would wear your pump.
