I just installed a Lane Lancet regulator set at 135bar in my S510 Carbine. The 173cc air tube limited me to about 22-23 shots at 3%ES at 28-30fpe. I did the initial install, cut my air pot down, drilled some additional holes in it and shortened my hammer spring maybe 3/8". I also polished the rail and ID of the hammer with some 1000 or 2000 grit sand paper, don't remember exactly which one now. I probably should have shot the gun before shortening the hammer spring, DUH!. It's shooting JSB 16gr at 875 average. I'm thinking now that the full spring might get my velocity up. Having lower velocities than I thought it should have I raised the regulator pressure to 155 to see if it made any big difference which it didn't so I set it back to 135. Anyway, now it's shooting a very flat string and I have something to work with. Once I get the velocity up a little with a full length spring I want to lighten the hammer for hopefully a few more shots. Here's how the string looks for now.

Very nice! That is encouraging. Why did you choose the RL regulator over the HUMA?

Airsupiorityproducts was out of them and the ones they had coming were hung up in customs. I'm a pretty impatient person. Not one of my strengths for sure😁 it's shooting really consistent now except for about three lower velocity shots. Might of been a bad pellet or something.

Looks good Jimmy. Let us know how it does after you work it over some more. I gotta say 45 shots with such a small light weight rifle and small air cylinder to work with looks very good. I cant wait to get around and reg mine.

In an attempt to get my velocity back up to around 880-900 on the 18.1's I ordered another full length factory spring after shortening the original when I installed the regulator. I received the spring yesterday and installed it expecting to see higher velocity but was shocked to see the same velocities and only half the shot count. I guess this is telling me there is way too much hammer energy so now I need to figure out the best route to get to my goal. I can always put the shorter spring back in and go back to a good shot string with 16gr pellets or go with the other mods to the hammer like trying to remove some of the weight. It looks to me like the after trying the full length spring and the velocity not increasing that would indicate the need for a higher regulator set point to get me somewhere in the ball park of my targeted velocity. Anyone have any thoughts as to my best options to try. I'd like to leave the regulator where it is if possible. Here is the string with the full length spring and shooting 16gr JSB's.

If more hammer spring pre load doesnt increase the velocity you have to increase the reg set point and adjust the pre load to the new setting.

Here is a link to a thread that Bob posted that goes into detail for tuning a reg correctly and explains the different ways you can tune them.

It's looking like a little more regulator pressure will be needed. I think I failed to mention that I had tried 150bar(1/2 turn on the regulator) and it didn't increase the velocity any but that was also with the shortened, weaker hammer spring so 150bar was probably too much for that spring. If I would have bumped it up to maybe 140 or so I might have seen a increase. Robert Lane says 130bar should yield 28-31fpe and 135, 31-35. But I do know Abslayer said he had to increase his to 150 to get the velocity he wanted. It'll just take a little time to figure it all out to get me where I want to be in the end. I am planning on reducing the weight on the hammer some today hopefully. Havent had a lot of time to play with it lately, too dang hot in the garage for one thing.lol

I got my velocities up to 892 average over 32 shots with 18gr JSB's or just a tad over 31fpe. My goal was 3 mags at 30fpe so I'm there. Wouldn't mind dropping that velocity down to around 875-880 and hopefully adding a few shots. I ended up raising my regulator today to 150 and shooting a full length spring and a slightly lightened hammer. I think maybe I can reduce the hammer weight and or spring a little and drop the velocity and add some shots. I did have three shots that registered low due to the regulator not doing its thing.

looks very nice, though I would have been thrilled with the first and longer string, only because I hate refilling when I am punching paper. I realize hunters don't need a bazillions shots (unless it is me shooting) so you have plenty

Looks good. I have my s510 carbine set for 26 fpe. If I stick a reg in it I will keep it set there and that should give me a decent amount of shots for such a small rifle. Shooting around here is starting to drop off and hunting season is coming up so maybe I will get the reg and work on it during the down time. Thanks Jimmy for posting the results.

Thanks Leland, that first long string with the 16gr was 27.2fpe so you can see what's possible at 130bar. I really prefer the 18 grain over the 16 so I'll probably concentrate on those strings. The tin of 16gr that I've been tuning with were in terrible shape, really bad bent skirts. The 18's seem to be a lot more durable. But, if the 16's out shoot the 18's then I'll go with them. I hope you go with a HUMA so we can compare. The Lane seems to be working pretty good other than a low pressure every once in a while as indicated on my last string.

I will get the Huma. I am inpatient also but deciding to do this project during the down time for shooting will take the edge of waiting for a Huma away if they are not in stock when I go to order.

Here the latest update on my project. I ordered four sets of springs to replace the one I got from RL that had a lot bigger OD and ID. After a couple of swap outs and test fires for velocity I cut one coil of one. I have more details of these springs if anyone is interest. So now with my regulator at 150bar, yes that is correct 150bar. I shot a string last night with JSB 18's. I'm really pumped with the shot count and energy but the ES and SD is more than I like. I'm not sure what's going on. I'm thinking the hammer strike for some reason isn't consistent on every shot. I'll get three or four that are within 1or 2 fps from each other then I'll get some goofy ones. I have caught on a few occasions my guns regulated pressure being low after the previous shot. It looks like maybe somewhere in the 140 area. But I'm seeing the wild fluctuations when the pressure is reading normal as well. Here's the string so If anyone has any ideas please pass them on. I'm going to pull the hammer and spring and do a little polishing on those parts this evening.

Ran another string with some el'cheapo 14.3's but this time I looked at my guns gauge and documented what it was showing before I shot the pellet and recorded the velocity. It turned out that it was very predictable velocity by judging what the regulator was doing. I thought I had spring and hammer issues but apparently it the regulator. Don't know if it will do any good but I'll send RL a note and see what he says. Go ahead and say it...HUMA? Attached is that string from tonight, looks very similar to the previous string.

It seems like the velocity variations have worked themselves out. I shot a string of 16's a couple of days ago and only had one in the middle of the string. I guess it just needed a little more break in time. I expected the first shot to me off but it was normal and the second shot was low velocity. Overall I'm tickled with what it's doing now. Attached is the comparison of the unregulated gun and the end result. The unregulated was only getting about 22-23 shots at 3% ES and under.

Nice. Better than your goal of 30 shots @ 30 fpe! Now it would be good to see a string with the 18.1's.

Jking · « **Reply #16 on:** September 01, 2015, 09:00:24 AM »

Here's the 18gr. I have the regulator set at 150bar according to the marks on the regulator. According to the guns gauge which I realize can be and probably is off a little the regulator is set at a little less than 150 since most of my recorded before shot bar readings are 140-145. Going with that, anytime the regulator refills and seats to either something quite a bit lower like 120 or higher than the 150bar the velocity is lower (highlighted in orange). Both understandable results but variations either way. Definitely not worth worry about right now.

Hows the reg performing Jimmy? I just ordered my Huma for my S510 carbine so hopefully I can get it installed and start some testing next week after I get it. I will post my results and settings when I get it done.

Jking · « **Reply #18 on:** September 10, 2015, 09:06:39 AM »

Thanks for asking Leland,
I haven't shot it through the chrony since the last posted string but everything seems to be ok. The gun is shooting great. Great groups at 50 if the wind isn't blowing and I do my part. I suspect the regulator is still not refilling the same 100% of the time because every now and then the groups will open up for an unknown reason. Don't think it me anyway. Then on the next group it's back tight again.

I received a Huma from Nick at Airsuperiority to try but haven't had a chance to install it yet. Hopefully it will eliminate the few fps variations and the annoying wheezing sound

Let me know what yours is set at when you get it and how the project goes. Looking forward to your results. Oh yea, don't forget if you need any springs let me know.
Jimmy

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.
