AA S500

I love my springers but have been wanting a pcp since I bought them 2 years ago.
So here is my AA S500 I found in the classifieds archive.

So far I have shot 3 strings, one each with the power adjuster @100%, 80% and 60% with AA 16gr domes.

First of all, hand pumping is a drag. Maybe more so for me as I don’t have much lead in my pencil.

The results I think are pretty good. The usable range appears be 200B down to 150B.
I get a few more shots at 60% than 100%, but when you get past 150BAR it starts dropping pretty quick.

At 100% the 16gr are smokin around 950fps/32fpe. 60% runs in the 780s/20fpe.

My China device records mps, so my fps numbers are not exact, but certainly directional. Seems to be 25-30 consistent shots with a few more when running 60%.

I am only shooting at 10m in the basement, so no longer range testing so far. I have Donny adaptor inbound so I can put a mod on it. Not that it’s real loud, but it must be quiet for me to venture outdoors.

With no hammer spring adjustment, I am sure it is wasting some air. Once I start tinkering with it, I will experiment with different springs at the lower power settings.

For now I will shoot it some more, and dream of a compressor.

Great gun you got there. I've had one but I don't remember what hammer spring options there are. The 18.1 JSB are also great pellets and that would slow you down closer to 900 which is perfect. The 950 with the 16gr might be a little fast but if it's shooting well go for it. Just know you have a great other option with the 18's.

Thanks Jking, I read every thread I could find and the 18 come up every time. The 16 were what I had on hand. Over time I will try many different pellets. Turning the power down will let me shoot some of the stuff I have on hand now.

I do plan on some 18s and others in that range the next time I order pellets. I need to wait for the all watching eye to lose track of me for a while before I spend more.

My s-500 likes the jsb 18gr heavy on the first notch below full power. I shoot almonds at 35 yds constantly. Also on full power with jsb 15.89 gr same poi.
