I've tried to before, but maybe it is time I try to drag him over to GTA again   I'll see if I can talk him into it,lol.

That would be fantastic. Maybe other pp700 users will follow him

Really not a fan of FaceBook, but forced to join in order to access posts in 4 groups... Now 3 and no access to previous posts–just vanished. The pinned link–vanished. Any mention of the groups existence—Vanished... with no explanation. Like it never existed, lost knowledge.

Facebooks' gotta go.

[Rallyshark]

I did link Klaus to this page, and he said he may have to come over and check it out.  That is progress   Of course, I linked him to the last page of the post.  His brain would explode from reading this one from the start,lol.

Great Donny.

Hey Guys... wintertime is toytime!

Because of Rallyshark i bought this gun in .22 + Huma Regulator + thread Adapter 

Huma was set factory for around 120 bar. I also screwed out the hammer preload vor 1,5 turns because i just got 20 shots of it before. Now its about 30ish. Couldnt mesure the fps because i have now chrony but i would like to ask you if you have problems with the LDC alignement with the thread adapter? I got a massive shift of POI and also bad accuracy at 6 yards with it. With LDC its also louder than a .22lr with ldc, much louder than the BSA Buccaneer with the same LDC. I guess there is just to much waste of air. If i screw out the hammerspring preload even more the fps goes down massiv.

Regards!

I also had an inconsistent POI with the addition of the LDC, tightening and rotating the barrel. Others posted here drilling and tapping a set screw into the barrel collar, keeping the barrel from spinning in it's collar. Under the rear sight is a great conceal spot to do this (thanks to whoever posted that!). Now I'm stacking pellets @ 15 yards with LDC tightening not effecting it, still have a slight LDC POI shift vs. no LDC which is expected.

The loudness makes me think you may be getting blow by on the breech o-ring where you load the pistol.  With an LDC, it shouldn't be that loud.  Put a piece of tissue over the breech/swing block and shoot it.  If it flies off, your o-ring is leaking.  That could also have something to do with the addition of the LDC/thread adapter.  As Thane mentioned, putting a set screw(or in my case two) on that collar at the rear that the barrel threads into is definitely recommended..  It sounds like everything is just loose really.  I put a set screw on each side to lock that collar down good.  A set screw hidden under the rear sight is also a good idea.  That way, you can properly tighten down that LDC, and the barrel will stay good a snug too. 

If the barrel isn't threaded into that collar at the rear, then the collar that holds the breech o-ring won't be secure, and the o-ring won't seal very well.  I'm with Thane on this one.  Get that barrel secure, then install the thread adapter and LDC.  Let us know how that works out for you.

Dont get me wrong, everything is really tight. Its really easy if you push against the Barrel while you turn on the Adapter. I could turn it even more, but i am afraid the Barrel cracks because  its so thin. I also got a lot of lead chunks in the LDC. But if i look through the barrel it looks like its perfektly aligned. I also got the loading chamber pretty good to seal after i screwed in the silver part of the valve body.    If i hold the LDC into a pillow its quiet as it should be. So my theory is that it dumps too much  / too long air so that the pellet gets another push after it exits the muzzle. Maybe i have to play more with the regulator setup /hammer tension.

Right now this gun really packs a punch and shoots through 15mm of MDF

Too much hammer spring can certainly make them louder than normal, because the valve is still open after the pellet leaves the barrel.

Thinking about putting a longer barrel on the pistol,for more accuracy and better power. What is the general concenus,chocked or un-chocked ,in .177. maybe aprox 2 inches longer. I have a lathe so can do the turning down,crown work myself.

The stock barrel is crazy accurate in my .177, and I don't have an issue with speed either.  Of course, I've done a lot of tuning to mine too.  I was able to get it up to 25fpe with the stock barrel.  The highest power with a realistic use is around 20fpe though.  If I were going to put a barrel on it, I'd probably go choked myself.  The 2 extra inches should net you a bit more power as well.  Hey I know, you could make two barrels out of a standard LW blank(or other 24" blank), if you don't waste any.  Order the choked blank, and cut it in the middle.  Then you can machine both halves into a barrel.  You'd have one choked and one unchoked then

Jfyi barrel length has ZERO to do with accuracy.

Received mine in 22cal last night.
Mini strip, backtogether and aired up.
435 Ave with 14 grains
Hole in snow at 15 yards and multiple shots go into same hole rested on deck railing. I am stoked
Only thing is wish the rear sight had elevation adjustment!

Hi
Had my .22 for a couple of weeks now, but not had access to a chronograph till yesterday.
I'm in the uk, so limit to 6Fps. The pistol was set to 3.3 Fps out of the box, so what is the best way to get the pistol to the Uk limit of 6Fts please ?
I don't want to play with the regulator, as yet I don't understand it to well.
Should I start by opening up the transfer port grub-screw to fully open ? Then use the hammer spring adjuster nut till I get to just below 6 Fps ?
Thanks in advance
Joe
Ps Ive included a pic of the pistol with my hey! moderator on it

"Jfyi barrel length has zero to do with accuracy"

Might want to research a bit before making such a bold all inclusive statement.

Please educate me. What has barrel length to do with accuracy?

[Traum]

I just got the folding stock for mine and am loving this pistol even more than I did before if  that's possible.

I need to try the grub screw into barrell I'm having similiar poi change's with ldc.. always thought it was the ldc not the barrell go figure.

[nervoustrigger]

Please educate me. What has barrel length to do with accuracy?

The only things I'm aware of are:

1.  With open sights, it increases the sight radius, thus the aiming precision.
2.  Longer barrel (in PCP & CO2, not springer) yields higher velocity which may be instrumental in getting to the sweet spot of the pellet's ballistic coefficient
3.  Longer barrel (in PCP & CO2, not springer) yields higher velocity which reduces impact of cant error. 

The first doesn't apply if scoped and the others are manageable with tuning and scope setup.

[bandg]

Sight radius was the main issue I was referring to and in the pp700 case it would not necessarily be applicable since the sights are frame mounted and not barrel mounted.  I would also consider that SHORTER barrels might be more accurate in some cases due to the quicker exit of the projectile from the barrel-high power springers for instance where vibration/movement might degrade accuracy.
