Artemis P15 need a help

Hello Kubi11,

Welcome to AGN! I'm glad to see that you made it! 
Hopefully, you'll get some responses to your questions much sooner than later.. 
We have a lot of P15 guys here, so, you are in good hands! 

I'll be sure to keep an eye on this thread, and chime in again if/when needed.

Best of luck, and, do some pawing around on the forum, I'm sure you'll really enjoy it here!

 

Sam -

Short barrel , 177 caliber is the problem. Wind can play havoc on pellets especially 177 and 22. If you are trying to reach out to 100,you need bigger caliber longer barrel something besides a Bullpup. I have 177 calibers and my max is 50 yards. 

I have 25 cal. I bought it to be a light walk around, shoulder shooting gun. Out to 50 yds. Thats what it'll do.

When you buy an airgun, one should try to identify what its principle use will be. Being new here I am assuming ( possibly totaly incorrectly), that you are fairly new to PCP guns. Its a learning process that never ends. 

Also pellet selection !!!

Get after it and have fun!

On Youtube, 

we chatted about pellet type, grain [weight], distance, wind, etc. being Big factors.. 

Most likely, it is one of those, so we'll probably need to know 'exactly' what pellets have been used:

Name Brand / Version / Weight 

There are a lot of P15 guys on here - Myself included [I just have the .22 version not the .177]
That said, I figured there are guys on here that have the .177 cal setups also, 
and may be much more helpful than me - when advising different pellet / power options..

Also, with the P15s, not-all-are-created-equal: 
For the most part, people have been saying that the factory/OEM barrels can be hit and miss.. 
Slightly different diameters going down/through the barrels - like little tight spots..

If it was due to something like that, I would figure most if not all shots would be erratic / random 
as the points of impact would drastically differ..

Since some pellets are impacting in a tight group at short distances, but opening further out, 
I'd assume that wind would be more of a factor..
Different shaped/style pellets and different weight pellets will all fly and hit differently too.. 
Then ballistic coefficient plays another part, but, I won't get into that one just yet either..

A bit more 'exact info' on the pellets used so far, and hopefully some .177 cal P15 guys will chime in soon too..

Think ill change the barrel to fx st x ) and for extra stability ill go for huma regulator hope that will solve the problem

Hahaha There ya go!  

Actually, a lot of people are changing the barrels.. 
They usually go with a higher end upgrade like the "lothar walther". A few guys here have them and absolutely love them!
You can find their threads / posts on here - using the search - and using key words, but I'm sure they'll pop in here also..

Huma regulator - That is probably also another really good upgrade.. 
I remember seeing other topics regarding the factory/OEM regulators, and how some didn't perform as well as they should, 
so people tend to also upgrade those.. 

I completely understand that in some countries, calibers and speeds are limited.. 
Exceeding those - and getting caught - could lead to confiscation, fines, and so on.. 
Other times, you'd have to register them the same as you would an actual firearm..
That said, it would be nice to get things figured out, so you'd have more of an 'all around' setup, while staying 'legal' too.

Kubi11,

Sorry, I keep forgetting to expand on the multiple velocities thing..

In most cases, you'll want to pick a specific range: say 15 m for example..
Set up some targets, and test fire.. Use different pellets [types and weights]
Find out which ones work the best out of the ones you fired..

Then from there - velocity - Fine tune that to make the 'best pellets' fire and hit even better!

Too slow, and they'll fly odd and/or drop to quickly etc.
Too fast, and they'll usually become really wobbly / unstable - and also fly off course..

Right in the middle is the sweet spot..

Tuning the power / hammer spring tension will also help with shot counts per fill..

Having a chronograph is a Big help!
I finally just got one and got it working correctly, so I'll be doing tuning on mine soon too..

Now, if you find the right pellets, and get your power all set for a specific distance, you'd be good to go..

If you change distances, that's where another power adjustment would come into play..

So knowing all of those things so you can pre-adjust is a nice thing..

[This is why I like to get rifles with adjustable power wheels - to adjust the port on the fly vs. having to use hst]

But then - like you said - you double that distance.. Now, all of the impacts are different..
From perfect to shotgun pattern..

That's again a few variables - the pellets, the speeds [destabilizing in flight] and/or the wind..

The farther you shoot, the more those variables are going to come into play - unfortunately..

*Cleaning your barrel, and making sure that the crown is in good condition are important factors too!
Derp.. I always forget to mention those things too..

Yeah, when we chatted on Youtube, 
Pellets was also one of the 1st things that came to my mind..

I had been dealing with that exact issue a lot with a new rifle, and it was driving me crazy.. 
Crazier than usual - I know - I know - It's hard to imagine. haha 

In my case, I had to go with a pellet quite a bit heavier to get things smoothed out, 
and after that, things were a day and night difference - for the better.

Set your gun to where you need it to shoot, at the max distance you will shoot, the most accurately. This is the hardest scenario to get right. Once you are happy with it at distance, don't touch the power, just try every pellet you can get your hands on at your closer range. Change the pellet, not the gun. It takes some experimenting (actually, a lot) but it is very cool when you find the right combo. Use the Strelok app to manage your ballistics with each choice.

+1 what he said

Yes but it doesnt explain why it needs 2 velocities 

265-270ms at 50 meters 15-18mm group and like a shotgun 100 meters and

285-290 at 100 meters 2.5mm groups and like a shotgun on 50 meters...shoots 1 hole at 30-40 meters 

Think ill change the barrel to fx st x ) and for extra stability ill go for huma regulator hope that will solve the problem

Thats because your pellets probably aren't flying true.

You could have one hole groups at 50m then move it to 55m and the group will open up on you.

You have what I call consistent inaccuracy. 

I've seen it a few times with my guns. 50 yards prints awesome groups move it 75 or 100 and like you day it's a shotgun pattern. 

Just mess with different velocity reg pressure all that good stuff until the wobble in the pellet is gone.

And may even try different pellets

Kubi11,

Nice, it sounds like you're starting to make some progress..
There's been a lot of good info and suggestions in here, so. thanks guys!

H&N Baracuda Hunters? That's great! 

I've had great luck with Baracuda. Even Better luck with Baracuda Match.. 
Baracuda Hunters and Baracuda Hunter Extreme are the 2 next tins here for me.. 

It amazes me that even the Baracuda vs. the Match version [same shape / same weight] 
worked that much better. They both shot well, but, the Match version were more consistent.

Best of luck and try to have fun while out there testing, 
and be sure to pop back in and keep us all updated!

Yessir, I agree 100% 
I've been extremely happy with their performance [actually, the performance of Both] so far! 
It'll be nice when the winter weather finally breaks, so I / we can get outside and start shooting at longer distances again! 
Personally - I'll get to re-do every single pellet test that I've done so far. 

Also, Updates - Awesome, thanks! Sounds like a plan!
