Paul, its easy to change but you lose the external adjustment feature which is nice to have while tuning.. tuning in the Huma is harder as you have to drain all the air and take it apart so it take more time.
    Travis knows more about the other question as I never shoot slugs or heavier pellets. 
    I usually keep mine set up for 18 gr JSB at 900 fps with reg at 110 bar and get 5+ mags. My stock reg worked best at 125 bar. The Huma is very quick to recover and the needle hardly moves no matter how fast you shoot.
     I've shot thousands of pellets through mine with no issues. I've shot the CPUM , 16 gr, 18gr, and 25 gr JSB  at various speeds without touching the reg.  I set my speed and sighted it in and the only time I touch my settings is if I change pellets for any reason. This past winter several of us went starling shooting in a barn at nite. I turned down my powerwheel until the CPUM were doing 350-370, then click my scope up until it was on at ten yards and I  was good to go. I almost emptied a full tin of 500 on one fill, probably about 375 to 400 shots. Never touched the reg. It was awesome.
I realize all guns are different so ymmv if you go that route. We have 10 or so Hubens in my area and most of the guys are shooting the 25 gr JSB with factory regs around 140. A  couple with Huma's at 110 and one at 150.

Thanks Randy.  I was thinking of setting the Huma regulator at 115 or 120, then I'd probably be able to shoot slugs and pellets.  I've been searching youtube to find a video that shows how to instal the Huma reg.  It looks as though it should be fairly easy, but how far do you have to tear it down to actually get access to swap it out?  I've not found any that just show how to disassemble it just far enough to swap out the regulator.  The disassembly videos I've found seem to go way beyond what actually needs to be done.  Any tips?

My reg. stays right around 135 BAR and with 21 clicks I’m getting low- to mid-900s with 25.4-gr pellets so this is good to hear.

Paul,
You have to drain all the air out of the gun, both tube and receiver. Remove air tube and screw apart removing the complete reg housing as the Huma comes with the housing assy which is threaded on both sides for the air tube. The new housing is different since its not adjustable from the outside. The new Huma reg adjusts via the brass screw just like all their regs but the air tube has  has to be taken apart to adjust. It is inside the front air tube. The new housing has a cut in the front threads for it to breathe. The regs we got in from Huma were preset at 145-150 but we turned them down to 110. You can call me if you need to talk.

Thanks Randy!  I'll hold onto your number, once the Huma Reg arrives, I'll give you a call to get some pointers on the actual disassembly.  The videos I have watched thus far are all full disassembly and seem like they go way further than I'll probably need to go to just swap the regulator. 

To degas, do you just turn the regulator down till the gauge shows zero?  To degas the receiver, is that just dry firing till it's empty?

On the disassembly, it looks like I may just have to remove the power wheel and the fitting under it, then take the big pin out and remove the stock.  Does the barrel and trigger have to be removed to swap the regulator?  Can I just loosen the bolts that hold the bracket between the barrel and air cylinder and then remove the silver regulator from the stock tube, then unscrew the air cylinder and regulator hosing from the section that attaches to the breech?  I'm trying to figure the least invasive way to get this accomplished.

I was thinking of setting the regulator to either 115 or 120 BAR when I get it.  145-150 BAR seems way higher than I'll probably need.  I have a bunch of slugs to test, but given the cost, I'll probably just shoot the 18 grain domes if I can get them grouping like my FX!  Thanks for your help!

To tear down for reg replacement this is what I do.
Mag sure mag is empty.
Turn powerwheel all the way down. Remove back cover ,  spring and buffer. Hold a folded up towel over rear and pull trigger. It will pop out open valve and hammer.  Let air drain completely.  Remove power adjust wheel and then with needle nose pliers unscrew adjuster.
Push out pin in front then remove from stock. Loosen two bolts on front band and slide off. Remove front bolt of main housing clamp and loosen two rear bolts then slide off shroud.
Remove trigger screw at rear that holds rod eye to link in receiver then slide off the main assy(scope rail, trigger and rod)
Take out screw and clip that holds airtube on and remove air tube and screw apart. Install new reg housing and reassemble in reverse.
Took longer to type than it does to do.

All that makes sense but the first couple steps:

Remove back cover, spring and buffer. Hold a folded up towel over rear and pull trigger. It will pop out open valve and hammer.

When you say remove back cover, spring and buffer, I'm not sure what you mean.  I don't recall seeing this step in the disassemble video!  I wist there was a video on swapping the regulator, Huma says there are no instructions, making it sound as if it should be intuitive as to how to disassemble it, but it doesn't seem to come apart like any other air rifle I've had!

...also have clear plastic baggies on hand, can't ever have too many of them...

Hey guys, I was just quietly following the post to see what I could pick up and learn.
Don't know if this will help but Gregor has a disassembly and reassembly videos out?
You guys are probably already aware of it as you seem light years ahead of me!

[Rat Sniper (AKA: PaulT58)]

Thanks Jimmy, the disassembly video is the one I was referring to.  And yes, it is long!  I will admit, I have skipped through it because I'm just trying to figure out the easiest way to just swap the regulator, so I may have missed something. 

[randy_68]

Huben used to have a video of reg replacement on their website and it showed how to do this. Looks like they changed their site now and I can't find it. You can also keep lowering reg pressure and draining that way but its recommended to pop out the valve. It's scary the first time but it's really simple. I need to take pics or make a video next time I do one. Just finished one up last week but never gave that a thought.

Here is the link. Its on Kelly's KraZCool page.
It's a little different as this one shows them putting the cover back on without the spring, then firing. I just hold a towel over the back.

Congrats on the Huben Paul, those are awesome guns, you'll love it...

Thanks for posting that Vid Randy. Had to save that one for later reference!

Nice gun Paul  I want the LCS sk 19  .30 when it comes out . I think that one will gov -stimulus myself / seller  pretty good !    , to hold me over I have a new AEA Challenger .357 coming in today AEA Bin Sig shooter on you tube tells me 125 g slug 900 fps out of the box ... 32 inch barrel available ,it should be able to push a 150 g pretty good around the 900 fps area , I bought the molds to do .357 pellets ,and slugs so I can shoot more big bore .357  stuff ,and depend on no one for ammo , I am no longer buying hardly any pellets or slugs just investing in molds ,and sizing dies ...

with that Huban I would defiantly cast for it , that one can eat a lot of ammo up in a hurry !   

[Tonycalves]

These Hubens are incredible.  Mine came the other day. Reg seems set at 170bar, and JSB 18s are screaming at 1078. Can't believe how quiet it is. Only had time to run 1 mag, very excited about getting to spend time with it this weekend. 

What mold are you gonna get for the Huben? I can see needing a ton of ammo.

Thanks Randy!  I see now why I was a bit confused with that step, I watched Gregor's video and he bleeds the air through the regulator and it's a two step process, this looks much simpler!

Do you have any links?  I've tried searching there, but come up with way too much contact!  Guess I'm not using the correct search terms!

Thanks Kevin, I am looking forward to blasting some rats with it!

That Challenger sounds like a real beast!  A big Bore, especially a full auto, sounds like fun, you will need a ton of lead for that one!

Congrats Anthony!  Check out Gregor's video on how to tune it for pellets, his reg is set at 100 BAR and he says he's getting a ton of shots with 18 grain JSBs at 950 fps!

Thank you guys for aiding me in my addiction, and pointing me to the good sh!t.
