I'm sure this lit of questions will show just how green I am regarding the PCP rifles and Regulators but here it goes.
- If I have a setting on a Huma Regulator of say 140 Bar should I still try and fill to the Max 200 Bar?
- Is it correct thinking that I could set one regulated cylinder at say 140 bar for 60yd shots and another regulated cylinder at 170bar for 100yd shots?
- If I setup my rifle and regulator (140 bar) to shoot a great grouping at say 60yds while the power level on the rifle is 3 of 6and afterwords I ONLY change the power level to 6 of 6 will it simply spread out my grouping or move the grouping center
I understand what I will be getting by adding my regulator. More shots at a consistent but lower FPS. I have ordered a Huma for my Hatsan Gladius .22 short and was just curious. I notice that when I load the cylinders to the full 200 Bar, on power level 3; I get 1 sometimes 2 flyers and then she calms down for a nice string of 20+ shots at 60 Yds. I have not tried to see how long that string can go but my guess is maybe to 40. I also haven't put the crony out yet because I knew I was going to regulate one of the cylinders and not the other (for the time being) so I will reserve the testing for same day, same weather, same pellet side by side.

1. You should fill the gun up to 200bar just as normal.
2. It depends on what you're shooting at, but leave it the same for all shots if it is targets. You don't necessarily need more power for better groups at 100 yards vs 60 yards.
3. It shouldn't spread your groups by changing the power level, but it will change your point of impact. The only reason it would change your groups is if the pellets are shooting way too fast to be accurate, but I doubt that would be the case unless they are very light pellets.
4. I have a question. Why are you shooting at power level 3? I would leave it at 6, unless there is specific reason for needing less velocity. I think your gun doesn't save a whole lot of air shooting on lower power levels, but I could be wrong. I would especially keep it on 6 if I were shooting over 50 yards, since there is no real benefit to shooting at the lower level for the most part.
Since we don't know what pellets and what speed they are shooting at, it is mostly guessing right now. I would tune the gun to shoot the pellets at the speed they are most accurate at, which is usually somewhere between 850-925fps. You could probably set the regulator at 130 bar and get that depending on pellets used. I use two separate cylinders on my Bullboss. I use one for targets that is regulated to shoot around 30fpe in .22. I have a second un-regulated cylinder that I only use for hunting, because I can really crank up the power on it if I need to.
I think you're only making things more complicated for yourself when you start factoring in power levels. If you want accuracy, you want everything to stay the same all the time(as much as possible anyway). I hope that helps, and welcome to the darkside where all your money goes away :D

Good stuff thanks. Yes I'm after target shooting for the most part but was unsure as to what it would take to nearly double my distance without somehow cranking up the power without having to increase my shooting pitch so to speak.
I shoot the rifle on power level 3 simply to preserve air and increase the shot string. Having gotten my PCP wings with a .25 MROD getting 16 shot dropping strings I was trying to be a bit of a minimalist on air consumption basking in the clip after clip after clip euphoria. Shooting Air Arms Diablo Field Heavy 18gr and H&N Baracuda Match 21.14gr has produced the best results though I have yet to invest in the other 6 or so possible matching pellets for the rifle. I started shooting the less expensive first. :)
I guess you could say I was looking at 60yd and 100yd shooting in the same manner you would look at Target shooting and hunting. You wanting the power for a cleaner kill whereas I wanting it for the further target. Kind of like this:
Non-regulated cylinder, a super heavy pellet on power level 6 shooting 100 Yards (Guessing 40 shots)
Regulated cylinder at 130 Bar, 18-21gr pellet power level 3 shooting up to 60 yards (Guessing 70 shots)
I hope to be happy with the results when i compare the Regulated and non regulated cylinders side by side but dont know what to expect at this point. Thanks for the insight and I'm sure there will be more information and questions once my Huma arrives and I barrow a crony for testing.
As for spending more money..lol.. you got that right. I still need
Carbon Fiber Tank
1 more Rifle Cylinder (to have 3)
1 more Huma Regulator
Test Pellets:
JSB Diabolo Exact Jumbo Express 14.30 Grains
JSB Diabolo Exact Jumbo Heavy 18.13 Grains
JSB Match Diabolo Exact Jumbo Monster 25.39 Grains
Crosman Premier 14.30 Grains
Bi-Pod
AR Style Foregrip (I like shooting offhand and want to try it)
and lets not forget a Hatsan Hercules in .357 or .45

Fill up to 200 bar,refill when goes under 140.
To my opinion and for the .22 set the reg to 120 bar
28 - 30fpe and minimum 40 shots

My biggest point that I was trying to make was that you will see very little difference in shot count vs the power level the gun is on. The Gladius uses a transfer port restrictor, so you're still striking the valve the same regardless of what power level the gun is on. You may see a slight increase in shot count, but not much. The only real benefit of shooting on the lower power setting is velocity control and noise level.
I would invest in a chrony, before I invested in anything else. Trust me, I was in the same boat, and tried to do everything without a chrony. Without the chrony, you're just as well off flipping a coin on guessing what your tuning is doing :D Get that chrony, and see what the gun is doing, then go from there. With a regulated cylinder and on power level 6 you should be able to get at least 40+ shots shooting at 30fpe, assuming you adjust the hammer spring accordingly. If you're mostly shooting targets, then 30fpe is plenty of juice even at 100 yards. Good luck and happy shooting!

Thanks for the feedback
My regulator will be here on Monday so for giggles I went out yesterday during a brisk 30 degree morning to clear the pressure one of my cylinders the fun way and was astonished to see the dismal shot count when shooting heavy pellets (h&n Barracuda Match 21.14gr) on power level 6. Maybe the weather had an effect on that, IDK. Your correct in that until I get a Chrony nothing really matters as that will pull it all together and I understood that from the get go. I was amazed just how sloppy those heavies were at 60YDS unregulated. I have only found two good pellets as of yet and they are both in the 18gr Range. Not sure I will even entertain any heavy pellets in the future a I don't see any point in it considering my intended use of the rifle. So far the way it has performed I'm thinking I may even be able to skip a professional tune all together. The rifle already shoots half dollar groups without a regulator power level 3 at 60 yards with an 18gr pellet with mild concentration. I have read about some people reducing the hammer weight after they install a regulator but I guess that's out of the question since I'm inclined to "maybe" on regulate 1 of 2 or 2 of 3 cylinders. Sure hope getting 2 cylinders set to perform exactly the same isn't to difficult. I will try and locate this thread or create a new one once I get the Regulator installed and buy/barrow a good chrony. Trying to make a pellet swap with some of the guys from the club to avoid having to buy to try other pellets. It's a real shame there aren't any quality variety packs out there. Everything I have seen and heard bout is full of pellets that aren't consistent and would be considered Seconds by most people.

You shouldn't have too much trouble getting two cylinders to shoot the same. You can get a chrony for less than you can get an extra cylinder, so it isn't too bad. You can easily get one for under $100. You will probably find that the hammer spring is too high after you put a regulator in the gun, which is where that chrony becomes vital. After you've played with it enough, you'll be able to tell when you have too much hammer by the sound of the gun too.
Unfortunately, there is no completely easy way to figure out what pellets your gun likes best. There are a ton of different options, especially in .22. You gotta remember that those Barracuda Match pellets come in 5.51. 5.52, 5.53 head sizes. You'll really need to find out which one your gun likes best. My guns seem to like the 5.52 head size ones. Those are great pellets for the longer ranges since they have weight and a good ballistic coefficient, if you can find a head size your gun likes. I've found that the pellets mine like can sometimes depend on how clean the barrel is too. It can take some time to figure out all the pellets your gun likes, but once you find the one, stick too it :)

The best money you can spend on tuning your gun after the reg is... pellets.
The more you shoot the better you will get,you and the gun.
Tip,learn your gun with the power adj. on 6 for ex. and always shoot with the same power adj.
MHO and only
