Hatsan  Hatasan Blitz 777

In case of the 777 there is a flat screw on the opposite side of the bottle pressure manometer.
Slowly turn it counter clockwise to release the pressure from the 700cc bottle.

Note: allow the air to escape slowly and do not remove the entire screw. Also pull back the charging bolt to cock the rifle when recharging the bottle (slowly) Decock the rifle when you are done.

Never leave the trigger spring cocked for long periods of time to prevent spring fatiqe

Which 12fpe Rifle do you shoot?

Hi Kenny,
A couple years ago I sent this Anschutz 9015 Black Air 10M rifle to Allen Zasadny who did some of his magic to bump the power level up to where it now shoots the JSB 8.44's @ around 11.2 fpe and the JSB 10.34's @ around 11.8 fpe. It gets over 99 shots per air fill. My Competition Electronics chrono only records a string up to 99 shots and this gun will max that out and still be going like the Energizer Bunny. He built the super quiet shroud for the barrel, installed the foster fill in the air cylinder, mounted the scope & rings for me and this gun is THE most accurate gun I own. AND, the most quiet. When you shoot it all you hear is a click of the trigger, a small puff of air, and then the pellet hitting the target. I could shoot it in the house and no one would know. ;)
In its "stock out of the box" form as a 10M rifle it was easily as loud as a .22 cal rimfire rifle. A BIG NO for residential backyard friendly.
I'm not quoting him here because I don't remember the exact conversation but if I remember right it went along the lines of this 9015 being a newer model than the earlier ones that sometimes had the POI shift issue. I have not experienced this running the Sightron SIII that's on it here in the Arizona weather. I have heard of this issue, but I don't have any experience with it.
Do you know if Allen sells shroud for 9015 without sending in rifle???

What did you do airgun related today.

A single shot loader for the Theoben Rapid mkii. Rook a few tries, but got it figured out and working.

The three versions. 1st one was a test for fitment. Things fit just fine, except the probe didn't close, and the 177 pellet didn't fit through the opening.

Second try worked great except it was really fiddly to get a pellet loaded.

Third was the final and works great. Still nice and tight in the reciever, and easier to put a pellet into the rifle.


Overall this 3d printer is a great addition to the armory!

Tuning  Umarex M1A1 Thompson Repair

Thank born2fly.
I am going on the 6th year (guessing... could be longer) with my M1A1 and at least 11K BBs thru it probably more judging by the large full box empty co2 cartridge's. With wood furniture... as I wrote before; "it is my favorite BB gun. I am thinking about getting another one and making some more "Kit videos" on how to improve and stabilize to gun indefinitely and making the kits to sell for those who want to keep them working.
The more I think about this, the more I think the right solution might be to modify the cone valve.
I’m thinking that the bolt needs to move rearward more slowly but still slam forward with enough momentum to activate the poppet valve. That sounds a bit like the way a shock absorber works. Not sure if I’d want to try making such a thing for this application.
Alternatively, perhaps modify the cone valve so that it does not close completely, but permits some gas to leak out the barrel instead of redirecting it all to push the bolt back (a small spacer behind the delicate little cone valve spring might work). Less gas pushing the bolt would mean slower rearward travel. Just so long as it gets back far enough to reset the trigger. Forward travel would not change, as it would still be governed by the bolt spring.
I’m just brainstorming …

The Real Science of Airgun Suppressor Selection

Hey there airheads!

The other day we sent out an email talking about all the years of experience we’ve had working with airgunners around the world—chasing down the best sound suppression possible in the airgun game. We got some great responses back, and thought, why not bring the conversation here to Airgun Nation and keep it going?

One of the big topics that came up was how air volume and internal design, whether it’s a monocore or traditional baffle stack, actually affect the shot report. Sure, there are computer models that can predict airflow and potential decibel reduction, but the reality is airguns behave very differently than firearms. They have their own quirks in how large volumes of air get expelled and how we tame that sound. Even though DonnyFL and airgun suppressors in general have been around for a while now, the science of airgun silence is still very much evolving.

When Donny first started this company, it was a lot of good old-fashioned trial and error. Just the other day, Yolanda was reminiscing about those early days, how she and Donny would stand out in the field doing A/B tests, swapping moderators back and forth, and listening closely to the differences in tone and volume. No meters. No fancy charts. Just honest, real-world feedback about what our ears told us worked best.

Over time, we’ve added sound meters and other R&D tools to the process, but we’ve learned something important: feedback from real shooters still matters more than any number on a screen. A meter might tell you it’s “quieter,” but your ears can reveal something completely different, especially downrange.

So how do you choose the right suppressor? It’s not as simple as picking the “quietest” one on the list. Caliber and power tuning matter, a hot-rodded .22 PCP can be just as loud, or louder, than a .22LR rimfire. Barrel system design plays a role too. Shorter barrels often have a sharper, louder report, while longer barrels can be sensitive to weight on the muzzle and may not play nicely with a heavy suppressor.

Then there’s how you actually use your rifle. In competition, suppression might not be the top priority, you might be more focused on how a suppressor can influence barrel harmonics. On the other hand, if you’re pesting in your backyard or working in a sound-sensitive area, maximum suppression becomes a must-have.

The quick and dirty rule is that more internal volume usually means better airgun suppression. But that’s oversimplifying it. Tone matters just as much, and in some cases, going with a really long moderator may hurt the balance or handling of your rifle.
We’re working on a comprehensive air rifle suppressor selection guide to help make those decisions easier. In the meantime, we want to hear from you. The best part about the DonnyFL community has always been the feedback we get from real shooters. We started out as a grassroots company right here in the online forums, and that community-first approach will always be part of who we are.

So, how do you judge airgun suppressor effectiveness? Is it tone, volume, group size, or a mix of everything? Got a favorite testing method you trust? Let’s make this thread a go-to resource for anyone looking to get the most out of their airgun sound suppression. Also, check out our full lineup of airgun moderators and air rifle suppressors!

Airgun vs chalk @50 yards

Just goofing around with my Beeman under lever shooting some chalk @50.... Harder then you think.
You're giving me an idea. What about using a steel tube just large enough for the chalk to slide in. Then weld it up so that the steel tube sits upright and allows about a half inch of the chalk to be exposed. You shoot the exposed chalk and get a nice puff of dust. Then the chalk slides down the tube and the next half inch is exposed for the next shot. I'm going to have to play with this concept. Thanks for the idea.
Kenny
