Impact compacts are bee's knees!

For the 13.4 grain pellets you might want to try higher reg, like between 130-150. The 177 caliber is less efficient because of the small bore size for the air pressure to work on. Key is to find the knee of the power curve. I know FX barrels can shoot the 13.4 grain pellets very well, you...

Very good shot count all things considered, pretty much same as a tubed dreamline at same power level. Surprised the high reg pressure produced poor accuracy, might need some fine tuning but if it's accurate now then don't need to change. Very cool, can't wait for mine.

My YH is almost 4 years old and at least 100 hours of run time. It keeps my 3 scba tanks filled because I use to use A LOT of air, filled my tanks from empty multiple times and topping off every weekend for a long while. Only issues were the crappy factory gauge and I upgraded the water pump...

These days the question could change to are the high dollar main brand compressors worth it?

My friend has Labradar and it’s PIA and registers half the time at best. I would look into FX true ballistics chrono if you are looking for BC validation.

Excellent work!!! I thought by having front clamp would negate the impact of temp change and those orings but I’m going to remove those orings also. Thanks for sharing your experiments and results with us.

My Dreamline 500mm with air tube get well over 100 shots from 230 fill shooting 12fpe. I lost count how many shots honestly.

El cheapo Yong Heng compressor from eBay in mid 2020, cost about 280 shipped. I fill 3 SCBA tanks then fill my guns. Very reliable except for broken factory gauge, has over 100 hours by now easy. Even fill 60 minute tanks from empty at least 3-4 times. The compressor is really quite easy to...

When I had my 380mm 177 barrel setup for HFT my reg is about 125 bars shooting 10.3 grain at 915fps. Very consistent, accurate and efficient.

Update: borrowed the gauge from my and pump and tried pressure test again and BAM it got to 4000PSI in a hurry! I said screw it, hooked up my 60 minute tank and let it rip. Basically a little over 15 minutes from 3200 psi to 4100 psi, woot! Not only it worked great but it also seems a little...

Thanks Gerry52! I kinda know the issue now and I also realized I made a big mistake! So I took everything apart again, add more oil the piston orin and made sure it is moving ok. Before I put back on the pipes I turned on the switch and it ran. Button everything backup and hook it up to test...

So my faithful little Yong Heng finally decided it doesn't want to go above 3000 psi after 3 plus years. So I ordered a second state piston which seems to be the most logical thing to replace. Opened her up and realized there is crack in the seal while the piston looked fine actually, so...

I added a stock to my 1701 for this very purpose!
