great!
huma air should really add plenum feature on their shop
what power do you achieve and shoot count with this new reg?

The problems with the first design was that A) the reg takes up a lot of space in an already small cylinder, and B) not all of the cylinders were machined the same, so regulator wouldn't fit in some people's guns.  The new design solves all of that.  The real plenum for the gun is in the receiver anyway, so there is no need to make the reg with anymore material than absolutely necessary.

I don't know what power Terry is getting yet, since he was still in progress of finishing things up.  On my gun, it is currently tuned to get 28 shots at 897fps with 7.25 grain pellets.  I can get it to push those pellets faster pretty easily at the cost of shot count.  Now, if I dropped my speed down to 750fps, I imagine it would be closer to 50 shots.  Keep in mind, I've done a lot of monkeying around with mine   In my opinion, the Huma is worth every penny!

Finished assembly and did a quick test with the chrony this afternoon. Cranked up the power to 725 fps and got 25 shots with JSB 8.4's. I want to keep the gun below 12 ft lbs, so for now I want to just scope the gun and make up my range card for an upcoming match a week from Saturday. Bell curve eliminated, and that's what I was hoping for.

After the National match next month, I may crank up the power and try out those Terminator pellets....

That is good stuff right there!  FYI, whatever you regulator is set for, turn it up 5-10 bar and recheck that shot count.  I gained 6 more shots on mine doing that.  They seem to really like being well below the knee of the curve(reg set a good 15-20 bar higher than needed to make desired velocity).  With my reg set at 125 bar it would shoot in the 940s with more hammer spring, but was an air hog.  I turned the hammer down to get it in the 900 range and was getting 22 shots.  I turned the reg up to 130 bar just to see, and sure enough, my shot count went up to 28.  Just a thought worth trying, if ya get froggy

I checked the reg before installing and they had it at 100 bar. I wanted to see what that setting would do, so now I want to crank it up another 5 real soon. Stand by. Your reg still sitting in customs, I imagine? Since you're on the east coast I would think you'd have it by now.

BTW, wouldn't the hollow section of the end cap act as a plenum?

Had a horrible day shooting the pistol. Two days ago I was able to shoot relatively consistent, not great, but pellets usually group within 2 inches. But today the shots are jumping up, down, left, right, by as much as 4 or 5 inches. Can not figure out what is wrong. It became more stable only after 150 bar or so,. This is worse than my experience with most of my break barrels. Hope it is something fixable.

I had emailed Mike about the breech seal broken issue and never got any response.

I basically bought my PP700SA for hunting so I'm not going to use it for competition, many are complaining about the reg in them not being that good but heck it does really good in the .22 version giving me 16-17fpe with JSB18.13's, everyone has they're own use for these guns and I'm fine with the stock regulator.  I think pushing the heavier .22 pellets this regulator is just fine and will be using mine the way it is until the spring washers give out (if they do).

If you're at 100 bar, I'd try it at 110. In most cases that area in the cap would act as the plenum, but the real plenum in this gun is the space in the receiver after the factory "reg". It has a tiny hole for the air to go into between the factory "reg" and plenum. The area between the Huma and the receiver has such small passage ways that it can't really act as a plenum  

[wimpanzee]

I pushed my regulator up all the way, and hammer spring in all the way.

I am now getting about 25 shots at 720-730fps with FTTs. Even overnight sitting, it only hit 731fps. That is good enough for me for plinking and small game.

At lower power levels, I did see a lot of creep. I need power tho! and that works well for this gun.

I had a huma in it, but wasn't really seeing a difference except fewer shots, so I took it back out.

Greg- if you don't have a chronograph, this pistol is a prime example of why you should have one.  I never used one in airgunning until I bought my MKII, and then a lot was revealed.  Shots I thought were more powerful were just marginally faster and wasting air.  I adjusted my reg for more power, then back off hammer spring until speed started really falling, then bumped it a hair back up.  I get a bit more than 40 shots in .177- about 6% ES.  Not great by any stretch, but for a pistol used at mostly 25 yards or less, it's the difference between 3/8" and 1/2"- very tolerable for squirrel.

And like wimpanzee just mentioned, these pistol like being on the upper end of that regulator flinging heavier lead.

Thanks Peter, the Caldwell G2 is on my wish list.

I suspect something more than the breech seal is wrong. But I will change the breech seal to see what happens. The shot to shot variability is beyond my imagination. Maybe I got a bad regulator? My AT44 is not regulated but I can pretty much put pellets in the same hole. I can shoot the P17 reasonably well, less than a dime from 15 yards. The Air max pistols trigger is harder to pull so that could cause some variability but should not be as crazy as I have seen last night.

I've held off as long as I could... but y'all broke me.  I've got my PP700 ordered.

Of you go in knowing that there is plenty of room for improvement with a little TLC they are a great little PCP and tons of fun. I have a Rocker1 carbon fiber LDC which does not upset the balance ( Very light )

We're all really good at enabling.  And when it comes to good choices, this is near or at the top of the list.

My coworker just received his.... Resistance IS futile!

[Sfttailrdr46]

  They are a fun pistol.

[Frank_Zuccarini]

I have two.  LOVE them..................... Frank

[YEMX]

I've wanted one from the start, but had so many projects in the works I held off...

But, I've completed a few projects since then, and threw caution to the wind and bought one.  From MrodAir.

Ugh, I'm only on page 6!!   

Not to thread-jack, but how long was the wait from MrodAir?
