Artemis P15 Owners?

[rc12ls]

I plan on buying two P15's , one for son also. I have 3 Lothar Walther poly .177 barrels. Even if I buy a .177 in a different gun , I'm still planning on trading barrels out and the .25 P15 is on sale for $350 right now... I shot a buddies P10 at a shoot and loved the Bullpup. So, this will be my son , and I , first Bullpup ..I planned on getting one of those 3D printed single loaders. Plan to shoot FT with it... Will74, "go with bigger components" ? You saying to keep .25 regulator but go lighter hammer spring if FPS to high with .177 ? Probably turn into air-hog..

The valve is caliber specific. One would think hammer spring as well. I would just go with the bigger components.
Magazines are about 30$ a piece...

Will74 , If , when you said valve specific, you ment the regulator, I just researched buying a regulator for the .177, .22,.25 and they're the same.. Even the pellet probe block is the same. The only part that had a different part was the pellet probe. Are you talking about the hammer and spring? When I was checking the parts , there were different hammer and spring kits for low and high power... So, I figure, there will definitely be a tuning curve... Thx everyone..

They list some parts for the valve in both .22 and .25. The valve body seems to be the same though.

I wouldn't worry about the reg or any other stuff when going smaller caliber. I actually believe it will increase efficiency. It's not going to waste air if you at least have your left eye on the game. I strongly suggest setting the reg to around 60 to 80 bar and start from there, hammer spring at minimum. No one has reg testers so it's going to take some trial and error but you will get there. Make sure to have enough air to fool around and take your time making SMALL ADJUSTMENTS. It will involve a lot of dismantling so make sure not to destroy them threads. They are very, very fragile.
Also something to point out, tuning like that will most inevitably lead to a double load. Most of the times they will shoot through no problem, but it would be good to have an appropriate rod to have them out in those unfortunate cases. It will be the easiest way to just remove the barrel, because the magazine won't always come off.

You might want to start by tuning it down in the original configuration. See how lumpy you can make the trajectory in light .25 and try to get some accuracy at the same time.
I don't think the gun knows what size projectiles it's slinging.

There's tuning potential up to 80J and probably more but it's going to take some effort. Even at that power level it shoots 2 to 3 magazines before falling off the reg.

Have fun

I get about 75 shots on my P35-177, maybe more. It is tuned to about 18 fpe. The spring was a bit stout so I shortened it but I should have just made clearance for the hammer spring adjuster to stick out a bit. I think the reg came set 15-20 bar lower than the 22 and 25.

Thank you .... I'll take some pics of new barrel machinng and the outcome of whole setup for and post them for whoever may consider doing the same. Can't beat the price.
