PP700 adventure started(Artemis PP700s-a)

[Wayne52]

Michael I'm sure that you probably surpassed the amount of shots I've had through my PP700SA however with you shooting them scorpian's like you do you've put a boatload of shots through that gun since you've had it.  I have had to replace a couple fill probe portal o rings but that's it.  I still have never really torn the gun down either, I remember Mike saying that when he ordered them from SPA that he ordered the good o rings with them.  I talked with him on the phone and he said that SPA gives the customers the options of ordering different o rings in them.

I received my .22 from  Canadashootingsports.ca yesterday. There are no leaks and the shot string is very consistent. However, it is the Canadian version with the tiny transfer port hole and is shooting around 488 fps with 14.3 gr pellets. I'd like to increase the transfer port size to get more velocity. Does anyone know the size of the transfer port hole on the full power version?

The OEM O-rings were definitely a weak point in mine.  At different times, it developed a leak at 3 different places.  Any time I had it apart, I took the opportunity to swap out the originals with a buna-N.  Whatever material they were, it would swell up significantly.  Most likely Viton but it’s bizarre they would use it when a less expensive material is better.

It is as big as you want it to be   Mine is a .177, so it won't do you any good to know what size the transfer was on it.  I opened it up anyway to around .17-ish on mine(I have no idea what it was prior).  You can safely go to up to bore size if you like, but I think you'd probably hit diminishing returns much over .185 on .22.  Going larger would only be useful if you were going for max power and opened up everything you could up stream too.  I think .15 would be a good place to start on an otherwise stock pistol?

Thanks Donny. I think I'll start with 5/32 (.156).

[WesBob]

I have one left in 22. 
One of the guys that spoke for it hasn't responded to emails so it's up for grabs.
I've got a few stocks left as well.

Thanks,
Wes

Let us know how it does!

I bet that will change to "had" real soon

Yep, gone 😁

I have not had mine out in a few months, been playing with other toys in the safe. The MKII is my Chinese Leshy. I need to find a bipod mount for the air cylinder. And yes, the giant DonnyFL is overkill but it does make it backyard friendly.

I slipped a DonnyFl Shogun on mine and woha. Did it go off? Yep, another dead scorpion. Love it!

whats the most power have you pp700sa owners gotten to? i got one to shoot 14.3grains at 765fps on stock regulator setting.

i can see the pp700 has two main problems, leaking air and regulator creeps and leaks.

[Wayne52]

duy I've only had mine leak from the fill probe portal twice and the last time I replaced it with a viton and has been good ever since.  The same goes for my Airmax Dominator, I've been hunting for a year now with no leaks since I put that viton in it.  When I first bought mine I turned the regulator up and backed off the hammer spring (it was cranked all the way in from the factory) and am still shooting just shy of 18fpe, I'm sure I could go higher but really don't need to.

[JungleShooter]

I'm shooting just shy of 18fpe.

I take it you're talking about the PP700 at 18FPE, right?
OEM regulator, right?


🔶 How many shots do you get at 18FPE?

🔶 How backyard-friendly would you describe it at 18FPE — maybe comparing it to a mid-powered springer .22 that PA usually rates "3-medium loud"?

this one i am holding leaks from the regulator adjusting hole. maybe its not sealing. i replaced it with my own pp700 regulator. opened the leaking regulator up, everything looks the same except the inside brass stem isnt in far enough like the working unit. no tools to play with, maybe later on. should be easy.

i feel 20fpe is the utmost upper limits. this one has 5mm exhausts with heavier hammer spring.

inside the breech has a .355 hole and max 3cc. i feel like installing a gauge and an external plenum.

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.

I have one coming from Canada Shooting Supply in .177, along with a .22 barrel. I’m pretty excited, and imagine I will work my way through all 90 pages for pertinent information.

Anyone that wants to refer me to a particular post or thread would be a blessing to this old boy.

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

[Hobbyman2007]

I’m still on my original and have had very good luck with it . I converted it to .25 and installed a HuMa pretty much right out of the box . I get 40plus shots at under 500fps with the 25 grain JSB . Mounted a Burris fastfire III with 3MOA dot and it simply wont miss what I’m aiming at inside 20 yards , typical distance for grouse hunting .
Still waiting for the 750 to be released just love these “cheap “ pistols . They are impossible to beat for the money.

[darkcharisma]

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.

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!
