air pumps

[klw]

I am new to air guns.

One question that I have asked repeatedly and never got an answer to is how difficult it is to fully charge either a AirForce Edge, Red .177 cal or a Alfa Proj Competition PCP Pistol with a simple hand pumpP Also how do you know when these are fully charged? 

 

[JamesD.]

It would take many sessions of 50 strokes, 5 min cool, repeat, for initial fill.

If topping off say 2500 to 3K, I'd think 100 strokes and not hard for me.

Look up proper pumping techniques on youtube.

You know it's full because all pumps have gauges. Newer AF rifles also have gauges & fill ports via foster quick disconnect

What JamesD said. I will add though that filling that pistol will be short and sweet. I have a Ocolot pistol and I can pump it up really fast and I would think that that comp pistol you have is close to the same size fill wise.

So the rifle might be difficult but not the pistol, right?

depends on what you call difficult. I have a Crosman 1701P pistol. Small air cylinder, but when you hit 2200 to 2400 PSI, pumping effort goes way up. It gets harder and harder as you approach 3000 PSI. The pistol, which is a 6fpe pistol, takes about two strokes per shot. A higher powered pistol will take around 3 pumps per shot. So, in my case, it's about 95 strokes to get from 1500 PSI to 2500 PSI, and I don't go past 2500 because it's a LOT OF EFFORT per pump where below 2500, not so much effort. If your gun is a hunting gun, it'll be closer to 3 strokes per shot, and getting up to 3000 PSI is a bit if a bear. The only difference between a rifle and pistol is the number of strokes. Effort per stroke is the same.

The pistols dont take too much, mainly because of the smaller volume air bottle. my 0.5L bottle takes roughly 3 rounds of 50 pumps to get to about 150 pumps to go from 2500- to 3000+ ish psi (or about 250bar I think) thinking the pistol is probably a third of that, so one round of 50 ish. not too bad. but you gonna tire of it quickly if its a long shooting event.

i have pumped up my AF standard size bottle via AF hand pump...that's why i now have a SCUBA bottle and HP compressor...
