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!

Re: JSB Exact Diabolo 10..34 Gr. – 177 cal

I've been using a Red Wolf , specifically configured for field target use, and while it only has three settings – Low, Medium, and High – I conduct pellet testing at each power to determine which works best for me.

I'm committed to multiple rounds of testing to ensure that any promising results are not just due to luck. Once a pellet shows potential, I try it again a few days later to confirm its consistency.

Usually, I shoot 10-shot groups at 25 yards which is the limit of my backyard range. Each 10-shot group is tested on the Low, Medium, and High power settings, and I record the data for future reference. When time permits, I take a curated selection to the indoor range for additional testing at 50 yards.

Over the weekend, I experimented with various pellets in the 10-grain range. While using the High power setting, I noticed that one particular shot group, the JSB Diabolo 10.34 grain, produced an extremely tight 10-shot group, with shots landing almost on top of one another. Although not technically a single hole, it was close enough for government work as they say.

Later in the session I decided to go back and add additional shots to the same group hust to see if it was luck or something else. After 40 shots in the same hole, the grouping remained consistently tight. The initial results were enough to convince me that this could be an excellent choice for field target shooting, which I already knew, but always looking for that confirmation.

I couldn't help but wonder if the outcome was merely a fluke. To ease my doubts, I repeated the test Monday morning, 30-shot group with the same results. Now… we’ll have to see how well all of that holds up at the 50 yd. range.

SIDE NOTE: In a different series of tests, I used the JSB Premium Diabolo match pellet, 8.44 grain, and observed some surprising results that I plan to post in a separate post.

Conclusion – Now I need a shooter as good as the gun, lol.

Post your benjamin discovery/s and their current setup/tunes.

At Palmyra Sportsmen's Association our August FT match is run as a shotgun start, we use timers, and closely follow the Grand Prix ruleset. This year we shot a one shot per target course with 20 lanes and 3 targets per lane across 20 lanes. The course had white lanes and black lanes, with white and black faceplates matching the lane color. Following guidance and information collected over the years, we attempted to setup the course similar to what may be encountered at a World FT competition. Those preparing to attend the Worlds in a few weeks got a chance to practice, and the rest of us got a chance to experience something similar to shoot a one shot per target course. A nice thing about one shot per target is not needing to wrangle strings and reset targets while shooting the lane.

It was sunny all day, starting at about 70F in the morning and getting to 85F by the time we were finished shooting. Although it was a nice sunny day, the sun made it challenging to range or see some of the targets that were in shaded or partially shaded during the day. There were light switching winds throughout the day.

The overall course difficulty was 30.1T. The White Course was 30.1T and the Black Course was 30T. No environmental modifiers are included in the difficulty calculations. There were many lanes where the targets were placed in a ravine, so there were several downhill shots on the course, and there were a few lanes that required uphill shooting. The 4 lanes that were located on our range had targets that were mostly placed beyond 40 yards. 25 of the 60 targets were placed at 40+yards.

The black targets were tough to see in the shade, but the color scheme was chosen because it is a WFTF color scheme used at many World competitions. We have heard it has been challenging to those that shot at Worlds and this was an opportunity to experience the same challenges the color scheme presents.

The forced position scores are used to break ties. The decimal number in the score represents the standing and kneeling scores for that competitor. There were two standing lanes and two kneeling lanes for a total of 6 possible points for standing and 6 possible points for kneeling.
Although Hunter Piston is listed as a separate class with one entry; it is notable that Brian Wagner would be Third Place Hunter (combined) with a score of 46, only separated from second place due to the tie-breaker.




Thanks go out to everyone that helped setup or tear down the course.

I expected to just pick it up,I did ,unfortuntly the butt did not come with the rest of the rifle,oooh booy, I'm just going to set up a jig and glue it back,no fancy pegs ,I hope it works,I think it will work ,I hope it will work....I should have been more careful

Two rifles in under five months.

First one went back for a barrel misaligned with the action, an off-center pic rail, and pellet probe o-rings getting shredded.

Replacement lasted 2½ months before it went full-on paperweight.

I expect to tinker after a couple years, not before I’ve even had a chance to really break it in. At this point, it’s less a PCP and more a hands-on course in “How Not to Build an Airgun.”

Good Morning,


My Notos is leaking air through the barrel. It won't take a charge. Anyone out there with ideas to what the problem is?? I've had it apart several times and tried somethings to no avail. I talked to Umarex and got nowhere. I've decided it will become a tomato stake if I can't fix it myself. By the time I ship it to Umarex and pay for repairs...it's not worth the hassle to me. Thanks in advance.

A friend posed the question ... "What airgun can I get to get rid of a couple of rock squirrels ?"
Now rock squirrels are notoriously tough and the dig like gophers on steroids and can destroy a lot of stuff by undermining, chewing it up, or eating it.
So having killed hundreds of these buggers over the years, I know what the challenges are. The problem is that she needs something easy to shoot, like a pcp, but I don't see her as accumulating and learning all the things involved in pcp ownership and shooting. So to me, traps or a CO2 rifle seem best as spring piston, pumpers, and pcp involve too much in peripherals and/or practice/knowledge to be practical plus there's the weight.
To that problem, I know my Sheridan F model could be pretty good with a red dot and there have been others like the Sharp UD2 that are simple to use and powerful but what is there CURRENTLY available? I went to the Crosman and Umarex sites because they HAVE had models in the past that might be practical , but current stuff is garbage ...
Any ideas for a simple to use, powerful enough (12ish ft lb) that doesn't require the learning time and weight of a springer or the support equipment of the pcp? The range is 30 yards and under and the cost isn't a huge concern, just ease of use, simplicity, enough accuracy, and weight...
Bob

This model can shoot bb's or pellets.

I've been out of the hobby for a while and need someone to fix up an old Daisy 880 back to working condition. Anyone have any recs? Thanks.

Having owned darn near every brand and price point of airguns available.... i find the most enjoyable thing about a really fine airgun, is a gentle shot cycle.
to me this means
smooth loading - easy access to the loading port
easy seating - getting the pellet into the breech the same depth every time
smooth cocking - for the bolt and hammer spring - or activation of the electronic firing system
predictable trigger release
minimal report (at my ear) from the action
minimal report (in immediate area) from the muzzle end
and lastly - no jolts or minimal muzzle flip

To date, no Airgun has beaten a properly tuned Redwolf. The gentle shot cycle of a Redwolf is my standard of excellence.

How about you? What airgun have you shot that has a truly gently shot cycle?

I kill 2-3 squirrels a day. That’s over, now. When I caught one with my garden tomato in its mouth that was it. I’m on a vendetta. Yesterday, I sat on my porch for several hours and killed over 20. Today, eight. Don’t mess with papa’s tomatoes. I’m a squirrel serial killer. I feel no remorse.

Hunting deer in Alabama 30 caliber or bigger. I have a Daystate .30 caliber, what’s is your thought about using it 80 fp? I would thing I need more power to take down a deer at 50 yards or less

Hello,
I have had this Crosman 2240 collecting dust and I was thinking about a project to upgrade it. I still want to keep it as a CO2 powered pistol, but I was thinking about adding a new receiver that would accommodate a barrel shroud. I'm hoping I can make it a little quieter for shooting in my shop. There are not a lot of options for high breeches, and they are also quite expensive. Do people have any suggestions? I have some machinist friends. Are there CAD files around that one could acces?

Thanks!

Thread 'Field Target is an arms race.' https://www.airgunnation.com/threads/field-target-is-an-arms-race.1324782/

Some variation of "the arrow or the indian" popped up in that discussion probably a good 30+ times. I recently ran across this quote and it gave me a good snicker.

"The flight of the arrow is as true as the skill and the nerve of the man with the bow." Attributed to the legendary Fred Bear.

Interesting thing about that quote is the 60ish years he spent pursuing better equipment. Obviously he was a businessman, and the parallel goal was surely to make money and have a successful company, but engrained in that business side of things was his perpetual march towards better equipment. He was granted various patents for his advancements in archery over those decades of the pursuit of "better."

Better might be the enemy of good, but I'll take better over good when it comes to my field target equipment any day for the week, and twice on Sundays.

Nothing new here really, just a reiteration that it takes "better" equipment, and "the skill and nerve" to use it to its capacity to win ft matches. Ie, those who win matches are those with the better equipment, and the work ethic to spend time figuring out how to get the most out of it (practice).

Anyone know who sells 3” diameter front rest feet pads? I have a set but need another set but can’t remember who I bought them from.

I have a ********l that I have had since 2021, but have only used a handful of times. I would like to sell it. Where can I expect to get a fair price. Online, or perhaps somewhere local (I'm in Central Oregon).

Thanks

My spelling might be wrong

Just was wondering on your experiences are underlevers more accurate than break barrels due to the barrel being fixed. Same calibers and fps and all.

Just saw this Sheridan described as 'Used but in excellent condition', and the $219 Buy It Now price seems extremely reasonable.
