48 shots from 865-830 fps. 40 shots on regulation around 853fps avg with 25.39 JSB kings. I'm done tuning!

I went through a "few" tins of JSBs tuning mine.
Heck when your shooting 56 shot strings......pellets get used up quick!

Lol I got very lucky when I tore everything apart and I put it together and that's how my tune turned out with no further adjustments. But that was just this time I burned through alot figuring out what the heck was wrong with it at first.

But yes finally I joined the group. I believe there is 3 you, shorty and now me and were waiting on John/fuzzygrub and Ozarkairgunner.

Way to go Dairyboy.....

Awesome work.

You sure do go through a lot of pellets. I have been using the 33.95's and still waiting for the 25.4's.

5 mags at this power and ES on our stock tube is just a pleasure to shoot now.

We have taken a 215cc SSG/SSS equipped 24/28 shot at 40 fpe and just under 4%ES 25 Mrod to a 40fpe SSG/SSS regulated 25Mrod with 40 "or more" shots under 3% ES on a 190cc tank.

That's around a 45% increase in shot count all under 3% ES. That's amazing...... I still can't get over it.

So Dairyboy,
What did you end up with for reg settings, TP, springs ect. ?

Ozarkairgunner · « **Reply #63 on:** November 08, 2016, 05:13:25 PM »

I'm still waiting the arrival of my reg with hopeful ambitions to join y'all on this 40/40 thing.

FuzzyGrub · « **Reply #64 on:** November 08, 2016, 05:16:09 PM »

No, I'm not there yet

I think I could get it slightly better as is, but the main gains will be LW hammer/light poppet spring.

Since we are comparing to prior work/tunes, it would seem we need to keep it to 3K fills. Right now, some of the numbers posted here are exaggerated based on over-filling.

shorty · « **Reply #65 on:** November 08, 2016, 05:29:30 PM »

Fuzzygrub is right.

PBguns is at 3200psi fill and I am at 36/37 shots at 3000 psi fill. Iam not sure what Dairyboy is at for a starting fill.

But,
As soon as those darn 25.4's come in, I hope all changes occur for me. It should and it should be real positive.

Dairyboy · « **Reply #66 on:** November 08, 2016, 05:41:22 PM »

Right now my reg is set at ~1950 psi or so. Normal Huma reg (without built in gauge port) and a hill gauge port. Hill .25 valve with light poppet spring. 28gram LW hammer from Rocker1 on a WAR SSG with heavy spring. .162 TP with .187 barrel port. Very little preload on the SSG spring and small gap. Mine was on a 3200/3150 fill so yeah was over filled. But don't think it came off the reg until 43 shots. So should be close to 40 for 40 on a 3000 fill but I'm not sure

Ozarkairgunner · « **Reply #67 on:** November 16, 2016, 09:49:27 PM »

Okay guys I know this kinda died off, but my Huma regulator just made it in recently and I'm hoping to get the results y'all have gotten, may start to install by this weekend. I'm going to start with my set point at 141bar and work from there.

Dairyboy · « **Reply #68 on:** November 17, 2016, 05:15:58 PM »

Good luck to you!

shorty · « **Reply #69 on:** November 17, 2016, 05:23:41 PM »

Can't wait to hear about it CJ.

I am starting to think nobody really cares about a 40/40 tune "or more" with their 25 cal marauder or if we are pulling their legs on it since it sounds so impossible.

Your gonna love it if it works out for you. If you need anything to get there, I would be more than happy to help.

Dairyboy · « **Reply #70 on:** November 17, 2016, 06:00:47 PM »

I was even skeptical about it while running it over the chrony and it just kept going and going and going

it's a fun gun now and as soon as I get a new scope for it will sight in to Polymags and have shots for all day

shorty · « **Reply #71 on:** November 17, 2016, 06:29:38 PM »

Dillion,
I know what you mean. Everyone knows me here as the "bad" guy or "troll" or "rude way" or just some dumb kid. Man, I have absolutely no reason to lie and I will explain and tell you exactly how I did it. That's what GTA is for........

Not only that, help you as a friend and not business person to make a buck to the best of my ability.

I do understand that there are vendors and pro's that are here to help with the people that can not do the mechanical work. For me, it's more about the DIY'er like us that can do the impossible.

It's just hard to prove it sometimes and get the idea past with a nice political speaking voice ( I have a hard time with that ).

When I started getting my first strings....that's exactly what I thought (I was in disbelief as the pellets kept going, and going, and going).
Then my concern turned to how repeatable of a tune is it? I have broke the rifle down twice (experimenting a little more), & every time going back to the tune is easy. I agree It made the .25 really fun!
The consistency still brings a big smile.

I think there will be 2-3 new members to the 40/40 club any day.
I read on another forum a .25/ssg/reg build, and how the probe was turned down a little to improve flow.
I still have a OEM bolt/probe, guessing that's a project for one of these nights. Can't imagine that having any negative impact on my stings....only positive.

I'm so deep in this tuning rabbit hole I can't see light anymore.

Mike,
As you know I am really interested in who does this 40/40 tune. Who are these 2 or 3 guys that are getting close and what forum.I can't find them.

The bolt probe mod is one thing I do. Although, I just don't reduce the diameter of the probe but pull back the shoulder (Pakprotector-thanks) for .18" barrel porting. For me and one other it created a 50 fps increase and the other a lower pressure tune at a higher FPE.

Motorhead "Scott's" bolt mod did not appear to utilize this on his bolt shaping build and under performed for a low pressure tune.

shorty · « **Reply #74 on:** November 18, 2016, 02:24:21 PM »

I really have to say this:

Bob,
If it wasn't for you getting out the SSG in Jan 2016, no one would have seen these numbers. Awesome work. You are a stand up guy for sharing this.

What is it with you Shorty

If you can't say something constructive turning near every post into some sort of P i s s i n g contest that your tuning efforts trump others work, don't say a dang thing !
The probe work you speak of was not required because we hit the target power & count customer wanted.
Those who seek MAX power and MAX shot count has no bearing on others work who were not after such results.

Enough already !!

Here's my number:

Call it.

I am off from work today. I ain't that what your painting a picture of me.

Shorty- my name is Tim. I really hate shorty. It's my cat's name. funny how that it is.

I'm sure when they get their tunes to where they want....they will share their findings. IMO its not my business to post their work (kind of rude, and stealing their thunder).
They will share when they feel they got to their tune (or need a little assistance).
I respect and value what Scott says and shares, there are less than 3-4 members on GTA that I really listen up and pay attention whenever they post.....Scott is top of that list.

Saying that I think modding the probe area on my bolt can give me a little extra on my tune.

My gun has a leak and reg is creeping but here's my last string. I took a couple shots to bring the regulated air down to normal pressures before starting string so no idea what starting pressure is.
