Filling by hand pump

I have the s510 long verson, not the carbine versaon. and I have day sate air wolf 230 bar rated.. 500 cc bottle.

I find both guns very easy to fill with a pump. I also have other pcp air rifles too.

if you need more info on this matter feel free to contact me.

​do u have bad arms or back?

​whats your weight, how often will you be shooting?

​what calibre will you be getting you gun in?

​all of these factors will matter in the long run
 
Its not too bad...I fill my FX Royale 500 by hand...as hasenpfeffer stated above...make sure you use your body weight....trying to pump with your arms will accomplish two things...frustration and tired arms. The key is to not let the tank get too low once its filled...I shoot my FX Royale 500 (unregulated) from 200bar to around 150bar and then I pump it again...that seems to give me enough shots for the work I put in to pumping it. Have fun! 
 
I had a Hatsan AT44 long and used a Flying Dragon pump which I'm told is an Air Venturi clone. I never had to pump from empty and I'm certain that would be a chore. Going from about 150 bar to 200 bar I would typically move the pump and cylinder into the den and pump during commercials while watching tv. You don't want to go fast; keeping the pump from getting hot is important. Doing it during commercial breaks and pumping slowly I could get to 200 bar in 3-4 commercial breaks easy. So that's probably 12 minutes total of slow pumping. My 17 year old son is neither strong enough or heavy enough to pump.
 
The hardest thing about filling with a pump is only the first fill...every other fill after that is always a top off. I gotta say most people that really complain about pumping are out of shape or just old!

Sorry to hurt feelings.. I am in my 30's and in shape, but I do see that most of you guys are up there in age (60-70). Probably not best to blow your back out :)
 
Well, I'm just 76, and I do have a hand pump. But, only because it was given to me. I can still press (over me head) 200 pounds, I can do 25 pushups, and my resting BP is under 125 over 70. Pump? FORGETABOUTIT! Even pumping from 1,700 psi to 2,900 psi isn't for the light hearted! To me, it is a good way to decide not to do PCPs. This is the exact reason I have a Freedom8!
 
When I got my Marauder a few years ago, I bought a mini CF paintball tank and the local paintball shop fills to 4500. The problem I had with it was I could only fill my rifle to 2900 with the paintball tank fill adaptor and it was hit or miss if the paintball shop could fill my tank. I'd get 7 fills per bottle and that went quick when I was tuning. So I went out and bought the Hill pump and I haven't looked back. I still have the bottle, but it's such a pain to get it filled on my time off from work that I never use it anymore. Now I have the Impact and pump it to 250 bar from 150. It sucks, but it's not too bad. I can have it topped off in about a beer. I am also 6 foot tall and 250 pounds. I'm in very good shape. Round. I said screw a six pack and went right for the pony keg. Ever since I have got the pump, my wife has noticed my arms getting bigger. So yes pumping sucks, but my wife likes me again so it's all worth it :)
