Regulated My S510 Carbine

[Jking]

Don't know if it will do any good but I'll send RL a note and see what he says.

Did you get a response back from RL? Would be good to know if it is a faulty regulator. Thanks for the info, I hope to get a S510 in the distant future.

He said send it back for a refund which I may do after trying the HUMA.

 That is good to know. What are your thoughts on the Altaros regulator. http://www.altaros.cz/en/air-arms/2-airarms-xtra-fac-all-models#/

I know that Matt Dubber put a RL reg in his S510 and the strings he posted looked similar to your string and to me was to jumpy. He was still working on it and trying different valve springs so it might get better. I am hoping the Huma reg I ordered will give better results. I know if I get a 30 fps ES with the Huma or any reg for that matter I am going to be really disappointed.

Robert, I personally don't know anything about them. I do believe that one O-ring on the end is the only seal between high and regulated pressure though.

I think Matts string was his first with no modifications to the hammer or spring. Don't know if he's done anything else to it since then though. What surprised me on his gun was that he got 30fpe at 130bar, as the regulator came from RL. I know mine and Abslayers had to be turned up closer to 150bar to get that energy. Could be just the difference in tuning. Maybe the HUMA will be different.

... the annoying wheezing sound

Mr. King,


I have also recently installed a RL regulator in my S510. (.177 cal. full size rifle)

Would you please explain the "wheezing" that you mentioned.

You bet, the best I can anyway. The sound could also be described as short high pitched whistle or squeak. It happens most of the time at mid string or later. Normally is just as soon as i pull the trigger but sometimes it may take as long as a second or two after the shot. About the only thing that I would think could be making that sound is the regulator seat in the process of seating. I guess there is also a chance that it could be the guns valve not seating perfect every time. I'll find out soon enough when I get the HUMA installed. What kind of shot count are you getting out of the 177?

Today I installed a HUMA regulator from Nick at Airsupiority.com. It had been recommended before but I got in a hurry and installed what I could find in stock at the time which was the Lane Lancet regulator. As noted I had issues with the set point not returning to its proper place every time plus an annoying whistle/wheeze/squeak sound after some of the shots. I happy to report the shot string is extremely flat over 33 shots until it falls off the regulator. There was also no hint of a after shot noise. Hallalluya!! Attached is a comparison photo of the two regulators and my very first string. I didn't make any changes to the hammer/spring setting just dropped in the regulator and put it back together. Hopefully I can coax a few more shots out of it when time allows.

What a difference. Looks like you got an es of only 10 fps for 33 shots and I believe the RL reg was closer to 30 fps for an es correct? I bet with a little tweaking you will get a few more shots. I get my Huma on Tuesday and as promised I will add my string for comparison.

Mr. King,

I installed the RL Regulator (set at 135 bar) with new valve spring in the reservoir with no other changes.
It is a .177 cal. S510 Extra FAC Super-lite full size rifle.

I had been getting around 30 declining shots in the ‘sweet spot’ firing from 150 to 110 bar according to the  gauge on the rifle.

If the charts load, it looks like 50 for now though I’ve only put 3 strings across the chronograph.

The strings also appear to be smoothing out.

Probably won’t get a chance to shoot it more for about 3 weeks … Work!

Mr. King,

It appears that the Excel documents didn't make the trip ...

The PITA way😁. For some reason it's hard to copy and paste if not impossible a XL file to a post. I make a Snipit of it and the download the Snipit to Photobucket. From there you can attach it to a post. Like I said a PITA.

Jim, that last string looks a lot better than the first two. I'd say it's getting about 50 shots before falling off the regulator and with only a 200bar that isn't bad. I bet with a lightened hammer and spring the shot count will go up. The next time you shoot a string check the rifle's gun gauge before each shot and note the pressure the best you can. In your first string it looks for sure like the gun wasn't refilling to it set point. Another thing you can do is polish the tube that the hammer rides on with some 1000-1500 grit emery.

Well I got my Huma a day early It was suppose to be in tomorrow but I am not complaining I am glad I had it shipped to work instead of home. I was able to get it put in today while I was working but I cant shoot any strings till tomorrow so we will see then how everything looks. It came set about 132 - 135 bar. I also found a light spring at the local hardware store to try after I see what the factory one is going to do. I also have some shims so I can get set on the knee of the curve. Im gonna wait until I try the factory spring and the lighter one if needed before I do anything to the hammer weight. But I have a lathe waiting in case it needs worked on.

[Jking]

Good deal Leland, hope it turns out as well as mine. I searched all over my town and found a couple of springs but never one with the exact measurements as the ones I ordered. The four different sets I bought from Century spring are all music wire with almost the exact OD,ID and wire diameter but with different coil counts and overall lengths which gave each one different ratings. Any issues with is holding air? If you smooth the ID of the airtube really well you wont have any problems. Keep us posted. I haven't touched mine since I put it in, just shooting and enjoying it..

Hi Jimmy just a point on my FPS and target shooting
The difference with you odd pellet going off line could be and most likely pellet inconsistency is most likely difference in pellet weight.
I weigh all my pellets and put them in groups that match each other it does make a big difference at range.
Yours is starting to look real good.

I left it over night and it looks lke no air loss. I shot a string or atleast I tried i got 13 shots before falling off the reg! At first I thought man I must have a leak so I filled it back up and got the same thing. So the 132 bar set point is way to low for the hammer energy I have. I didnt think it would be that bad but evidently its wasting a ton of air. It is shooting an average of 874 fps with 18 gr. JSB and its noisy compaired to normal so that tells me its pushing allot of air. The lighter spring I have is to light so im gonna reduce hammer weight then play with spring tension if needed.

Yea Mel, it could have been or maybe a bad skirt. I stopped checking the guns gauge between shots because it never failed to return to it set point. "dang" good regulator..Nice shooting by the way. Mine seems to be shooting really well. We've had wind for days but it looks to be grouping really well.
