Question, can i turn in the allen screw of the regulator with the cilinder under pressure or isn't that safe?

Can do it under pressure.

[nervoustrigger]

For general knowledge, with most if not all regulators, increasing the setpoint while under pressure is fine.  However when adjusting down, there is a potential of the valve seat getting damaged by being squeezed too hard.  In the case of the OEM regulator in the PP700, its not prone to this sort of damage due to its geometry.  But in general, if you’re adjusting down, it’s a good idea to either empty it first or make small adjustments and fire a shot to bring the plenum to the new, lower pressure.

Hi, you monsters and your discussion got me to buy a PP700s-a .22, got mine from a 2nd hand dealer so I'm not entirely modifying from scratch.

Never had an airgun, this felt like a nice one to try, feels very powerful, but I was concerned by the accuracy, so I taped down the gun to zero the sight.

It turns out this silencer/shroud it came with (that threads on/off) seems to be what really butchers my performance, does anyone think this likely to be an issue with the attachment itself? or thread? length?

Also as many people have said the gun seems to leak air pressure, for me till it reaches around 10, I charged it to 15 for the shots above, I have a huma arriving so I'm hoping that will fix it
The gun came with some spare o-rings (should I presume these are garbage?), so maybe I'll pop those or some new ones in too.

Ordered some..
H&N Terminator Airgun Pellets .22
H&N Silver Point Airgun Pellets .22 (Most excited for)
Tried the...
H&N Sniper Magnum Pellets .22 (Most Accurate)
Norica Devast .22 (Seems faster and flatter, but they're not kind on the breech, their tails seem to rub the seal, maybe my getting them in the barrel to shift left/right, not sure!)

I've been using "power pellet lube" that came with it, I've not had any combustion using it (I'd like to keep the gun safe), not sure how people feel about using it.

Should have a Chronograph soon, looking forward to doing a bit of tinkering hopefully!

Maybe you’re having clipping issues with that really long LDC.

[SuperCaffeineDude]

Maybe you’re having clipping issues with that really long LDC.

That's certainly possible, not really sure how to fix it, not worthy but I guess I could buy a shorter LDC, I'll try cleaning the old one out, maybe even tighten the barrel first.

[JungleShooter]

Just found out:

The Godfather of Airguns, Tom Gaylord, is doing a multi-part review of the PP700!   

Here's part 1 at the Airgun Academy site, fresh off the press:

Looking at your photo, I can see that you taped the gun down over the top of the barrel - this will deflect the barrel down, and thus your POI after you remove the gun when you are done sighting in will be high compared to how you set it.

You would need to have the tape go over the reservoir and not touch the barrel for that to work correctly . . .

I noticed a POI change when I clamped my PP700SA in the vise using the shroud. I think that is alot of your issues.

[Harold999]

Got myself a chrony and wanted to know how much power i can get maxed out.
Turned in the regulator and hammerspring but the result is not very impressive. Going from 10fpe to 13.
I'm hearing +20 fpe numbers from people. How do they do this?

I found the sweet spot on mine at around 16fpe with FTT 14.66gr. I got it up toi 19, but that was wasting a lot of air. I have all stock components, regulator turned all the way up and power only adjusted with the hammer spring.

Are you on 177 or 22?

[Thane]

I can get 13 FPE for 40 shots from .177 very consistant 2% ES with SD 3.9. I could pull more power, but shot count drops dramatically as well as consistancy.
8 FPE will deliver 60+ shots for me with massive change in SD 43, not worth it.

You just have to find the sweet spot.

.22

Turning the allen bolt in (clockwise) goes not that heavy is it?

I thought turning it out increased the pressure - which, depending on hammer strength may increase or decrease velocity.

To test, I would put the hammer strength on the high side, then test adjusting the regulator in and out to see where you get.

[Pelletjunkie]

When I hear the term “turning it in or turning it out”, I get concerned. The stock reg has a very small operating range. When you get it set to where you can visually see on your chronograph where it drops off the reg, your adjustments in or out are on a very small scale of “turns” to get to the minimum and maximum of what the stock reg is capable of. I am talking 1/8 turn then test. It takes very little movement once you are near the max of the stock regs capabilities to send it into the bypass mode.

A guns accuracy also has a lot to do with the guns harmonics. You killed that by strapping that thing down. If you are not a good pistol shot, several different kinds of sandbags can really help you get the gun supported nicely so you can just focus on your trigger squeeze for accuracy testing.

[SuperCaffeineDude]

Taken on board everyone's comments, obviously made a few errors in my first foray testing this out 
I've been shooting pretty well unrested without the shroud, I'll give the shroud another shot this weekend, regardless I'll change how I fix the position of the gun as many of you have suggested, cheers for the feedback!

Quick question, I've seen the O-Ring sizes posted...

1.5mm X 4mm Metric Buna-N 70
1.5mm X 5mm Metric Buna-N 70
1.5mm X 8mm Metric Buna-N 70
1.5mm X 9mm Metric Buna-N 70
1.5mm X 11mm Metric Buna-N 70
1.5mm X 12.5mm Metric Buna-N 70
1.5mm X 13mm Metric Buna-N 70
3mm X 21mm Metric Buna-N 70

With the breech o-ring though I've read a few of you recommending HNBR/HSN, could anyone tell me what the o-ring on breech measures at in imperial? Would rather not tear the gun apart if I've nothing on hand to replace anything I damage , trying to find them on theoringstore

Cheers again,
Jon

[Pelletjunkie]

The breech is the 1.5x9mm. Buna 70 or 90 will do.

I’m pretty sure the cracks of this thread have seen this seller of custom PP700 parts, but just in case you haven’t, I just stumbled on this today and thought I should share:

Reading T.R. Robb’s personal airgun story is amazing     –  he’s been shooting and gun smithing since 1959, that’s TEN years before we put a man on the moon. The airgun collectors will love to read about all the models he mentions. You find his story here:
   https://www.trrobb.com/page/about%20me



So, there a quite a few interesting PP700 parts on that website:

And as you read through them, could I ask for YOUR ADVICE??   
I don’t have the gun yet (due to my location at the end of the world it will take some time), but I thought of ordering the fill probe and the quick connector in stainless, as the thread showed a pic with the fill probe really dented – “soft brass” said the explanation.
Anything else I should get while I’m ordering? What tools will I need to replace the o-rings once the gun gets to me.

This guy has a host of other stuff. Amazing.

OK, I’m done enabling now. You may go now, click on any link, and spend money without remorse. As you can blame it all on me.

Side note: In the UK they call the PP700W the 700W or the “Green Grip” – and they call the PP700S-A the “SMK Artemis,” or something like that.

All T.R. Robb had when I was building my PP700 was the fill probe and the gauge removal tool.  *FACEPALM*  But I'm glad to see more tools coming out.  Especially since I'm wanting to build another one (or two!  ) of these pistols...
