    Huben 22 GK1, is this keyholing?

    400 fps with CPHP, 5m away and target is 1 meter above shooting position. Not sure if keyholing or hanging chad because of angle. Stairwell is only place to shoot without windows nearby.

    5k burst on a 4500 psi DOT buddy bottle, why?

    Bought a 1.8L buddle bottle new, 4500 psi working pressure, DOT paperwork confirms it but it uses a 5k burst disk. Im sure ill get a blown disk pretty quick if I fill to 4500 so i never do. My bigger bottle uses a 7k disk. Is this just so it passes DOT hydro tests without damage? I only intend...

    3d print settings

    Wanted to share CURA 3d print settings that I found helpful for better prints. Eliminated fitting/reaming I had to do on mags so they'd spin freely. Iniital Layer is for removing elephants foot. Hole is for making the holes slightly bigger so mags fit together better. Seam alignment is just do...

    Snowpeak Lancer/Snowpeak T-Rex Carbine

    Added cheap CVLife picatinny bipod, Monstrum adjustable picatinny scope rings and 3-12x Bugbuster scope. Used and removed a piece of cardstock to shim rings up in the back. Have to wait till weekend to shoot it. The french forums mention a 2 week old free 3d print "M12x1.75mm" accessory on...

    .22 Darts Milbro

    Got a Snowpeak SP500 pistol to try darts, the only .22 darts I could find are these Milbro Black 0.222. It does 4 fpe with 14.3 grain CPHP at 355 fps. These are about 21.2 grain, I average 50fps or 0.12 FPE with them. The package says they are mild steel. After shooting I see no rifling marks...

    Snowpeak Lancer / Snowpeak SP500 .22

    Noticed Lancer started selling SP500 .22 break barrel pistols on Amazon for $47 shipped, goal is to have dartboard pistols. Ordered two. Both barrels tilt to the right but was able to move rear sight mount to compensate and keep sight centered and it might be getting better with breakin. Finish...

    10mm burst disc that doesnt blow below 4500psi?

    I wanted to swap burst discs for a better brand. Do any of you have chinese compressors that you fill to 4500 reliably? I figured id just buy that brands disc and holder. Mine blows from 3500 to sometimes 4200. Almost out of discs and its a weird size I need to get overseas. Also, not sure why...

    Snowpeak Lancer/Snowpeak T-Rex Bullpup

    $210 on sale on Amazon from California. Noticed Lancer started reselling quite a few new snowpeak models this month. Excited to try it and compare with Notos. Regulated, tanks much larger, barrel is almost twice as long, dont need to do bipod or scope ring mount hacks. It does say Lancer in the...

    Vevor / Yong Heng relay / breaker / thermal protection

    My Vevor Yong Heng clone kept blowing the builtin 20 amp breaker. I didnt measure current yet, but based on the builtin voltmeter it didnt seem to be overcurrent related. The orientation of the contact pads on the breaker in relation to the piston vibration seems to be the culprit (contacts...
