Calling all 25 cal marauder REGULATED guns

[TerryH]

Just out of respect for Shorty's thread on regulated 25s, I would recommend starting your own .22 cal Armada build thread so these guys can get back to the OPs original topic.

Will do. Was stated a couple posts back.  Sorry for the hijack, Shorty!!

No problems here Terry. Just to help you out, here's a table of stats on my 22synrod when it was NOT regulated. Porting was at .141".

Bob,
What your saying is so true with high power and regulated shots as it sits now with what we have. Although, things are going to change soon with this additional auxiliary plenum.
Just think, this drop in part (experimental and on the drawing table) should be able to bring those high power regulated shots with a "stock-looking" configuration.

I just need to work harder or get a few others on board. I firmly believe this auxiliary plenum can get a 22 to 40 fpe for 35 to 40 shots and a 25 cal to 65fpe+ for 16 to 24 shots while being able to tune it back (with a hammer spring adjustment) to a medium power level for efficiencies over 1.9 and all on the stock tube making the gun look like it's in it's stock configuration.

Shorty, I have always been impressed with your dual wire spring and the numbers you get with it.  I would love to try one with my setup.  I have watched your videos a number of times using it.  I have not received the TSS test kit from Travis he talked about, but I know he has his hands full with the TSS launch and he may have changed his mind about having me test it. 


Like you, I can appreciate the efforts it takes to come up with a new mod.  My DIY SSG and F.A.M.E. mods took a lot of time and effort to develop.  I gave the ideas away for free because it takes even more effort to launch them and support them.


The TSS idea came from your time and efforts creating the dual wire spring and I for one will always remember that.  You have come up with several really neat mods in the recent past including the SSS idea that I pay close attention to.  keep it up!

I would have sent a couple to you if you asked. I just don't have enough wire to make them anymore.

With the skills that you have, I have a feeling you can make one or better.  Here's the video on how to make it:


Go on amazon and search "music wire" at what ever size you need. Music wire will work just as good. Piece of cake.

Yes I have watched that video a few times.  You do make it look easy.  I'll have to give it a try.  Thanks!

So I know this kinda died off a while back but wanted to let y'all know I finnaly joined the 40/40. Took me a while to save up money for a few new parts, Hill light hammer and Hill valve with 6lb valve spring. I got 38 shots on the reg averaging 763fps and the last 2 shots just barely making 40fpe at 752fps and 738fps. All using the JSB MK2 33.9

[kkarmical]

I should be more than happy with my 29 shots,  but my string isn't as flat and I just feel there's a couple more shots hiding inside of it, that last shot I rushed.  But still 29 shots @ 52 fpe ain't too shabby for now...
I think next for me is to explore different springs with this ssg/mds combo or maybe go back to stock hammer for now I'm pretty stoked getting down to 5%..

With that inconsistency in velocity, I would consider polishing the hammer tube. Check out Travis Whitney's Youtube video on the subject. Of course, he uses a ball hone of the correct grit, but there may be another way. I know this can make a big difference on Marauders.

[kkarmical]

I think there's too much spring with ssg/mds combo, should be able to flatten it out by trying different springs at some point.  I was getting 24 shots that were really all over the place  12-14% es, so I backed it down a bit and ES came down it ain't perfect by no means but single digits + 5 more shots was a good compromise with where I am right now.

[triggertreat]

That's a good many shots with good power no doubt. A high ES can be caused by many things. You definitely would want the hammer sliding as consistently as possible to rule it out.  Maybe clean the air tube and hammer free of grease and dirt then put a little dry graphite under the hammer. That stuff really works well on mine.  Makes it really slick to slide and doesn't attract dirt so much.  Good ventilation on both sides of the hammer is good to have also.  Good luck.

I found my best efficiency at  .185" porting but I didn't try THAT many combinations of tp sizes, primarily .201" (my exit port size), .185", and .171"...efficiency at .171" and .201" were nearly equal which I found odd but at .185" I achieved better efficiency. I can't say a .05" size difference will equate to much for you but that's my observation.

The erratic fps could be so many things, but if the reg is broken in then its either too broken or isn't  able to perform at 1% es or better at that power level...could be a few other things but with the MDS hammer its less likely, but maybe something in your ssg setup is causing it? Worth investigating, idk how yours is built...

That is a great shot count though for the power you're obtaining, if you want a few more shots to give you another clip I would reduce the power down to 825~ FPS...

I'm going to shoot it a while like this and see if it settles down, but I think it's ssg/mds it's so smooth and easy cocking I can just tell there's too much spring for it.  I might try the stock hammer and see if I can make a change.

Also it may have been me as late night shooting I may have rushed more shots than I thought.  I may try tuning reg down a bit.

Also I think I could have taken 2 more shots, so I'm going to leave it set like this, shoot it for a while, then shoot another string take more time between shots and see if that alone brings me closer to that flatline.

Too much spring has never caused my tunes to have a bad ES, only when coming off reg. On reg the only thing that really wrecked havoc on my ES was metal hammer galling and even then my es was 2-2.5%...

I highly suspect the regulator can't handle that high of power as well as say 40 fpe. JMO. Also if you have a VERY small plenum for this power level, that will cause this effect...as you dont have enough potential FPE in your plenum...

Lets just ASSUME you have only 20 cc plenum (as I once did)

That would give you a potential FPE of 384.. (this doesn't mean max in 1 shot, just what is available total as you can't expend all of this in one shot)

For the 50+ FPE you're gunning for you IDEALLY want a potential FPE of  AT LEAST 700...IMO. That would require a plenum of 39 CC's (@ 2k set point) to operate efficiently...

Your plenum is likely struggling to perform at that power level. I bet you won't have an erratic es like that @ 36-40 fpe

I also suspect your plenum volume is around 10-15 CC...or something crazy low. (200-300 potential fpe)

Hope I can save you some time, pellets, air and frustration as I am pretty sure my diagnosis is spot on. GL

Also too low of a set point for the desired FPE can also cause a higher shot to shot inconsistency...FYI, by creating the same effect as above.

I know this is an older thread. I own an Aramda and want to improve shot count as well as accurcey with a workable power level which is not the most important.  I have ordered a cheep eBay regulator to tinker with and mod, and I have a Huma with gauge block and portport for the permanent setup. I have every thing in this forum on moding the Marauder gen II, but most of it has a cause and effect problem, like hammer gualing  hard cocking, and the Armada can't have any thing sticking out back of the hammer tube, because of the stock. So I also picked up a drop in Steve HDD current design unit from AOA. I have been thinking of get a used marauder stock to do the tuning with and then locking every thing in to a permanent state then back into the Armada stock. Has any thing evolved to reduce the need or hammer mods, and othe problem?
Thanks for any help.

P.S.
 This is 25 cal new Armada. I need to fire a few more strings to get a broader data base. I contacted Scott about a tune rom him. Not knock on Scott, but didn't get much hope of achieving what I want. Being an engineer with a lot toys like CNC mill, and lathes as well forging power hammer. I just don't accept the word can't.

Talk to Rocker1 he can make you an MDS hammer or several other vendors also make drop in MDS hammers

I was thinking about turcite instead of MDS and 12L44  as the hammer to get close to the stock weight of the stock hammer. Turcite is used to repair matching tool ways. They can carry a lot of weight and will never wear out or deform under pressure. It is oil proof and does not scratch under grit or dirt. It is capable millions of cycles under extreme load. I have used dry film lubricants that can eliminate metal to metal wear under extreme loads and conditions the may work very well on metal hammers?

Going to install a Hill valve, increased volume gauge section and Regulator in my Armada. I was woundering if a depinger is needs to be installed also. I hate the ping when you fire it. I will be using it for pest control and don't want to run everything off after the first shot

The regulator should take care of the ping for you.

A short stiff spring solves the problem of an SSG sticking out of the back of the gun. Just as efficient without all the work.
