PP700 adventure started(Artemis PP700s-a)

[Pelletjunkie]

I'm up to page 50 in this thread, and wow, lots and lots of details.

There are a lot of takeaways here that are exceedingly valuable, but my immediate concern before the pistol arrives is how many times the O-rings have been mentioned. Several posts indicated the correct sizes, and since The Oringstore is just over an hour up the road from here, I ordered 20 of each ring except for the largest 3mm x 21mm, of which I ordered only 10.

There is one consistent theme here, shared by me, and that is everyone is anxious about when their pistol is supposed to arrive, lol!

The orings were a good investment. Another piece of advice is be patient with the reg. The list of guys who had luck with it is about the same size as Powerball winners but I noticed a common theme. They just shot the gun a whole bunch without going for the velocity brass ring. But if on day 3 you decide to chase the velocity dragon, make very tiny adjustments to the reg. I mean tiny 1/8 turns. The bad news is with the stock reg, I see a lot of guys do the fire 2 shots at the ground before they do any shooting or post a Internet shot string. The stock reg is capable of a very tight string but it’s a creeper.

My reg has been great, but I never cranked it up to max which seems to bring on the creep/flattening the very small belvilles.

Mod I wish was done immediately, would have saved me much grief, is adding a barrel set screw under the rear sight. Even more important if your swapping barrels.

I will be reviewing this great thread again for results on the most accurate pellets (0.22 & 0.177) for the PP700 but if comments are offered it would be interesting. 

[Thane]

The starter of this thread RallyShark put me onto the .177 H&N Terminators, produces some nice and tight groups. At 7.25 gr you can really stretch a long string out of a fill.

[Rallyshark]

Unregulated, I got my .177 over 25 fpe with 15 grain sniper magnums(opened some stuff up ).  I think it would get a little more with heavier ammo.  I currently have it tuned to 13-15 fpe depending on ammo.  I feel pretty sure it will do 20 fpe with the Huma in it.  I'm sure a .22 could probably get close to 30 fpe opened up and unregulated.

How many shots do you get with your .177 set up for 13-15 fpe?

I get 30-35 shots depending on how heavy the ammo I'm using is.  I generally just tell people 30 shots,lol.  That is a great power level for a little .177 hunting pistol though!  It is currently tuned to shoot the H&N Terminators at 900fps for 30 shots.  It is pretty flat shooting with that tune

thats a good base line Donny. i haven't played without the reg yet. i do like the reg and the current 19fpe at 10mpa. it can only go up with pressure

5mm is the most i can bore the exhaust to. any larger and we will ruin the countersunk valve seat.

i never thought i would settle for 765fps with 14.3grains but its accurate as heck at 25 yards!
25 cal is cool.

They are a lot of fun at any speed!  If you do decide to play with it unregulated, you'll have to make a plug to go in the rear of the reg housing, so it will hold air without the factory bits in there.

Thank you Frank. It has been my intention to shoot the gun as is for at least 400 to 500 rounds before trying much of anything in the way of adjustments. Winter is about to set in here in Eastern Washington, so I’m going to be shooting in my shop 99% of the time (it is 40 feet wide). I don’t need to go for higher velocities until Spring has sprung.

The O-rings are a just in case sort of thing. If I’m going to replace any of them, I want better than stock. At the price I paid (around 16 bucks shipped), I believe I have enough to last the rest of my natural born days, lol!

Took the better part of yesterday evening, and about 6 hours today (off and on during errands and odd jobs), but I have gone over the entire thread, plus looked at a myriad of suggested threads and parts.

Pretty sure I’m going to dream about this darn pistol tonight, and mine isn’t even here yet!

Otony, I'm right there with you!!  😄

[Lammy1000]

Which .22 pellets are the most accurate with this pistol?

[Wayne52]

Lou I always shot the 18.13's from my .22 but it always did use it for hunting only.

[rumbleUU]

My newest PP700s-a 4.5mm wich have never leaked air from the day it arrived, I "think" it is leaking now, If I remember right it was at 180 bar 2 weeks ago now its at 130bar.... BUT I can be wrong, I really dont remember... Having many airguns is confusing remember everything 

Anyway, I did fill it up to 160 bar now, dryfire it 2 times , took a picture, and we will see if it leaks...

this is so frustrating as this was one of the best I have, ready to shoot with homemade foldable stock and sighted in... So I hope its not leaking..

I did check quick, its not leaking on the area between the silverpart and tube, thats good..
What else to check?.... I also checked the tube joints, nothing, fillport hole nothing...

I hope I was wrong and it holds pressure, but just to be prepared if........

Good morning
I've reviewed the thread and may have missed it.
Is there a complete list of all the O Rings posted?
If not, Anthony, will you please post a copy of your O Ring store order?
Thanks

Duy, If anyone can figure out a reliable fix for the stock regulator creep, I'll bet you can.  Mine creeps (along with my friend's identical gun) and is the only thing keeping this pistol from being perfect for me, other than designing it as a carbine from the ground up.

[Thane]

The reliable fix is a Huma Regulator.

[nervoustrigger]

Regarding the O-ring sizes, they are given on SPA’s exploded diagram.  Just be aware they use the wrong convention for describing the dimensions…they list the OD.  When you’re looking for replacements on theoringstore, McMaster, Amazon, etc., they will instead be described by the ID.  So if SPA says M2x14, you will need to order M2x10.  In other words, subtract the cross-section twice (the “2” in M2 in this example).
 
Another example might be M1.5x8.5, in which case you would need to order M1.5x5.5.

Regarding the creeping regulator, the fix is described here:

Thanks, Jason
I'll search up the exploded view.
Yes, as a Freedom & Liberty owner, I am up to snuff on the Chinese protocol for listing O-Rings
Thanks for the reminder

I just received my order from orings and more yesterday. I ordered a complete set of the m1.5 o-rings in the following ID sizes: 4mm, 5mm, 8mm, 9mm, 11mm, 12.5mm, 13mm. All are Buna-70 compound. The only other size used in the pistol is m3 x 21mm. Hope this helps.

I agree 100% because I installed one in the two PP700's that I own which resulted in very consistent shots.

Very helpful
I just downloaded the exploded view.
Now I can see which ones go where
