I installed the Huma Regulator today. Thus far, it doesn't seem much different, but it's a brand new regulator, so I guess time will tell. Before the install I ran two full magazines through it. Here's the before chrony numbers:Shot count: 38Low: 905Hi: 981Avg: 923Spread: 76STD Dev: 14.7981963937928930919921928912926914921937930932914921919923907919930926923916905905923928921909914923923909905907919The top picture below is the groups, shot in 5 shot groups.The tear down and install was pretty easy. I did a combo of Gregor's and Kelly's instructions, so I turned the power wheel all the way to zero (17 clicks), then removed the power wheel. I then removed the back plate off the breech, pulled the spring, replaced the back cover and squeezed the trigger. It took about 5 minutes for all the air to drain from the air cylinder. I pushed out the pin holding the stock, remobved it, then remove the front barrel band. I removed the small bolt from the linkage ar the rear of the rifle, removed the 3 screws securing the trigger and scope rail and slid it off. This it was just a matter of removing the one screw securing the air cylinder to the breech, give it a 45% turn and slid it out. From there, I just unscrewed the front and rear parts of the tube, removed the Huben Reg and replaced it with the Huma reg! Examining the Huben regulator, I was able to confirm it was the older version. Reassembly was just as easy, just reverse the process. Once it was all back together, I filled it with air and apparently killed my Benjamin Recharge compressor in the process! It wouldn't fill past 3300 psi without going into a death wobble! Trying to top it off to 300 BAR with my Benjamin Traveler caused it to shut down do to it pulling more than 30 amps! It took letting it cool and starting over to get it to 300 BAR. Once filled I did another 2 full magazines over the chrony. The second picture below if the groups after the Huma reg was installed.

I screwed up and shot 5 shots without flipping that little lever down. This cause the Huben to dump about 200 BAR of air and jammed the magazine up solid! I was able to get working again, and all seems fine now, it's just hard to shoot when you don't have a reliable way of filling it! In any event, had a great visit with Randy, and I sure do appreciate his support!

Humm RKR, I just measured my favorite hp. Mine! 1.96 mm. It would just fit! Paul, be careful. some have has problems when shooting at low pressure where the mag did rotate, but did not push the slug or pellet out ot the barrel. Unfortunately, they thought he gun misfired and tired again. The slugs were stuck in the barrel. GRRRRR! Actually returned the gun to get it cleared. (I think we could do it ourselves just fine) Mike/Knife

That will settle in and get much better as all Huma's do.Thanks for sharing budSignedThe Slacker
I've had a few times where I shot with pressure too low, and had pellets stuck in barrel. It is a big pain, but they can be pushed back down, 1 at a time, into an empty magazine hole, and then can be extracted from the magazine, or just fired out, after airing up. A little squirt of Balistol, or something like, will help. I use a 1/4" steel rod, very carefully.
