To me this is no good Its on video but reshootin today .It was windy yesturday and i didnt wash and lube the slugs 4 shots in .821 of an inch. Wih the flier 1.552.So today i reshoot.And with little wind and clean ammo they will be tight and fast. Speeds were fron 1109 to the last at 1053 the flier .that one tripped over a piece of lead causing it to slow and spiral. Check out my post on washing your ammo.This is why posted it for you guys 
pics and video coming tonite

Tuning 100 yard group 15 inch BARREL p12 1100 fps 177 with slugs

Just out of curiocity may I ask why did you chop 18inch barrel to 15inch? Also on some previous post you said you are running regpressure at 3800psi or something and filling to 4500psi so I assume you have custom made airtube, valves and regulator since stock snowpeak/artemis/spa/mrodair or W/E P12 is only rated at 2900psi/200bar fill. Give us atleast some pics of that gun.

What is the noise level like for your setup? I am slightly interested in getting a .177 slug shooter.

I have lane reg set at a little over 4000 psi.As for airtube i call the manufacturer and was to they were tested to 8000 psi and i was good to fill to 5000 psi. Barrel was cut to remove the choke and then the barrel was lapped the oldschool way.As soon as the wind calms down i will shoot the video and post it.And i will also explain alot more about the gun .I bought over ten of these guns to customize .I will go over the features and why i chose that platform.

All you here is a ping.from the hammer.If you can find one i can show you how to cut the barrel and how to polish it.And i can show you how to modify the valve. I have one more left to mod and ordered the poly 177 barrel in 24 inches.Do you have access to a lathe.

Get on you youtue search tofazfou. And look at his 17 call airforce airgun. Watch the speed and accuracy.He used a greenmountain barrel, which is 172 cal. His barrel cost 80. dollars.If you get on walther barrel site you can get a poly barrel for 120, dollars .\, and the you can shoot any 177 slugs.172 cal take a special size slug. Watch all his vids.

You know thats really dangerous right? Filling 2900psi chinese aluminium pressure tube to 5000psi is like playing russian roulette.. eventually it will blow up and kill you.. snowpeak all it says about test cycle is 5000fills from zero to 2900psi.. interesting enough I always thought P12 barrel is unchoked

How about an avenger .The shoot slugs very well.And i can show you how to prep the barrel for even tighter groups.

I understand with the short little barrel, a sip of super high pressure air is going to launch a slug cleanly. And maybe it takes over 1,000fps to get that pellet barrel to shoot them well. But what I can’t understand is shooting an IED every day. Shooting dumb little bullets out of a pellet gun is not worth risking getting maimed or dead.

Agree. As Albert Einstein said, the difference between genius and stupidity, genius has its limits!

That is the absolute dumbest post I’ve read on this forum yet. 5000psi in a chinesium air vessel. You must have a death wish. Please , please , please do not try to reproduce this with any 2900psi air cylinder. Never , never , never overfill past the manufacturers recommended fill pressures. Simply irresponsible to post where complete newbies can read this and think it’s acceptable.
Responsible manufacturers with lawyers and qualified engineers typically use a 3:1 safety factor. What is posted here is no where near that. Simply foolish.

Intelligent people are full of doubts, stupid people are full of confidence. That's a quote from a German writer, I can't claim it, or remember his name. It seems to fit a number of recent posts.

Even though they test it to 8000 psi doesn't mean that it can be refilled to 5000 psi repeatedly and it will eventually let loose and it won't be good. . thought I was pushing it refilling a old carbon fiber tank which has been outdated for a couple years

Starting to wonder if the gun exists or if it's all Bs no pics no video overfilling a Chinese tank not even a 2 to 1 safety ratio and thinks it all right to do so kind of scary to mess with that kind of pressure like that

I do remember the Artemis P12 can be filled past the 2900psi mark as I have read on the GTA forums. BUT...The big BUT is I don't do it or advise people to do it. IT is fking "PRINTED" 2900psi fill for a reason!!!
The P12 uses the P15 airtube, so the manufacturers claimed. But Please dont fking fill it past 3600psi.
The only Airtube I would fill to 4000psi is the ATI Liberty airtube, because it's printed on the tube for 4250psi fill.
