How many pumps to fill these pcp rifles?

Jump to latest Follow Reply
Hey Kavliaris,
Boy, if I were using those bottles, I'd get a compressor.

I used to pump everything. My largest bottle was 213 cc's at 200 bar. IIRC, going from 100 bar to 200 took about 110 pumps.

If I was U, I'd get the Xisco compressor of something similar - mine cost $500 and has worked flawlessly for two years for my two RAW's (480cc - 250bar).

I understand your logic... I really dont have a problem pumping I am tall and strong enough and I have the patience for pumping. I dont want to spend money on compressor its not for my budget... But I would be stupid if I bought the hardest to pump pcp so thats why Im trying to figure out the whole pumping calculation

I used to hand pump my first Impact back in 2015 or 2016. That’s a 480cc bottle on a regulated gun. That means a lot of pumping. I’m not going to lie, having the coolest $2,000 gun at the time but dreading tuning it because of all the pumping got old quick. I could have been in a Bowflex commercial after 6 months.

Kav-

Depends...on the "pump", along with the size of the air reservoir on the gun. !

1) Pumps may have different volumes in them, from pump brand to another, that...makes a difference.

2) If you "complete" a full and complete cycle of each and every pump action, vs not a "complete" cycle...that makes a difference.

3) If you just start slamming pump cycles without stopping for a second for the last bit of air to enter your gun from the pump, at each cycle...that makes a difference.

4) If you pump the entire volume of air into the gun, without leaving it sit a few minutes to cool between pump cycles...that makes a difference.

So...there's a coupla things to review. And as you might notice, there are no...100% comments there !

Just buy the gun(s) that you want, the pump that you want, and start pumping. When the gauge says that the cylinder if full...stop pumping.

As mentioned above, your main question should not be the total shot capacity of the rifle, but how much air is needed to furnish the number of shots you need before topping off. The smallest and lowest pressure cylinder or bottle that provides the required number of shots is what you want for hand pumping. A rifle that has way more volume than needed isn't bad, but it might result in a bigger, heavier rifle than needed. If I were buying a hunting rifle for the kind of low volume shooting I do, then a 200 bar, small cylinder carbine would work fine.

Well I am looking for a pcp with 60+ Fpe and 50+ shots per fill (under 900$) so a 200bar tank with low cc wouldnt be possible for what I am looking at

No it would not be possible. I get about 60 shots at 60 fpe on a 250 bar 400 cc tank. I also want to make sure you understand pumping a PCP tank is quite a bit more challenging than a bike tire. I'm also a big guy and in shape. I'm a 240 lb former powerlifter and still work out daily. There is absolutely no way I'm hand pumping a PCP meeting your desired requirements on a regular basis. It would not be fun. LOL

I understand😂. Im not gonna shoot on regular basis though so... I will either buy one of the above and pump it for half an hour for a high shot count at good fpe... I also have an alternative... Umarex origin .25cal ±55fpe 100 pumps for 40 shots...And costs almost half the price of the other pcps that I want. The only thing that keeps me from buying it is that I wanted a semi or full auto at .30cal. I will see

I agree.
I started with an Umarex Origin and a hand pump. No sweat. Then a TalonP. It was not an issue hand pumping its 213cc bottle but then I put a 330cc tank on it. I can still hand pump it but it is a chore.
I wont even consider hand pumping the 500cc on my prophet, so I do it and the TalonP with a compressor now.
The compressor was $500 well spent!

I suggest the Origin because it is more economical to pump. Start a budget and save up for a good compressor. The prices keep falling and the quality keeps getting better.

How many pumps to fill the Origin? You bought the .22 version or the .25?

@Kavliaris, In either this post or your other about pellet penetration you never mentioned what your intended "purpose" is that you're trying to accomplish with an airgun. Are you wanting to hunt, plink, competition shooting, etc. & with which particular gun. You'd probably get more specifically helpful info. If you're looking for your 1st PCP I'm pretty sure a lot of people would say stay away from semi auto or auto PCP's. I know this is "off topic" but just trying to help.

Yes of course, I understand thank you for trying to help me. But I ask specific things since I know what rifles I want, my only concern is that I will be hand pumping the rifle.😂 Thats why I wanted to know about the whole pumping situation. So that I wont pick the hardest to pump rifle... As for the penetration since I want a .30 caliber but not a very high powered one, I wanted to know if there are penetration pellets at this caliber like the hornets of lower calibers and there arent any... Since there arent any at .30 then there is no point for me to take .30 caliber at 50-60 fpe when I can take the same fpe from a .25cal . Now I will either go with a ±55fpe at .25cal where penetration pellets exist(H&N Hornets,Skenco black max,ultramag) ... Or I will go with a .30cal that has over 80fpe so no need for penetration pellets since the power is much higher and will penetrate anything regardless the pellet type... I hope you can understand what I am trying to say. (english is not my main language so sorry if I dont explain properly)

A 25 cal origin while I don’t think will get you to 60 fpe it will get over 50 and you will be able to live with pumping it. They say from zero to 3600 psi it takes like 120-130 pumps I believe. However there are two wonderful things. The first being you will only fill from empty once. The second being there is no reason to fill that gun to 3600 as you are seeking power and accuracy. The fill really only needs to be to about 3000 to 3100. That will put you in the heart of the power and consistency. You will probably need to refill every 15-20 shots to keep the high power and consistency but that won’t require a ton of work. Another option is an avenger. Also very powerful in 25 and I regularly pump mine from 25-2800 to 3800 regularly and it isn’t bad.
