Practical example of GX CS2 gun fill time

I was refilling my Caiman X yesterday and used my CS2 because my bottle was getting a bit low. The Caiman X stores 285cc of air at up to 300 bar. My bottle was under 250 bar. So I fired up the CS2 and, while I waited, made myself a toasted English Muffin as a snack. By the time I had my muffin toasted and buttered the gun was at about 280 bar and I called it good enough. Another good way to spend the time is to fill a magazine or two. Doesn't really take that long.

Daystar Hunts!

Have noticed that the Turkish guns come a little over sprung and benefit from some tuning.
Agree. For the pellet weights that most people like to shoot many of the Turkish long rifles are over-sprung.

With the spring the rifles come with they get good velocity with the heavier 22gr pellets for a 'cliff' tune. However there isn't enough spring, and air volume to achieve a 'bell curve' tune with those 22gr pellets and get many shots per fill.

Picked up an older rifle for hunting this fall

WOW" how do you pump it up"? What kinda pursuer"
Here is a picture of the pump. It is similar to a bicycle pump, but makes much higher pressure.

The tank would screw on one end, and there is a part in the case that attaches to the opposite side to stand on. There's also wood handles that would attach to the end with the tank to use to push/pull the pump up and down.

I've been using 700 psi in the tank. Which should be similar to what the original pump would produce.

Picattiny rail for AA TX200

I only use something like a BKL. No two dovetails are cut the same with the same widths. If you get something with a side clamp your scope axis cannot be perfectly centered on all dovetail rails. Since the BKL flexes in the center it will mount dead center of virtually all dovetails.

I have a UTG adapter that I started with and mine shifted a lot until I added through bolts to really clamp it down. I dont use it for scopes anymore after trying a few pairs of BKL dovetail rings.

I would suggest looking at the wider versions BKL makes if you are concerned about recoil. Also keep in mind the mass of your optic also plays a role in the mounts shifting. If you are using something light weight it will probably never be an issue anyway.

Snowpeak  GOT MY PINTY BULL PUP...LOVE IT!!! BUT.....???

I was shooting my Pinty Pup last month & I heard air escaping. Then it would not take a fill. I contacted Pinty about sending me another poppet & valve if they had any. They said they don't carry those parts & sent me out a new rifle. So far so good. My replacement is holding air fine & very accurate. In the new rifle they also included among the spare o'rings & silicone grease a new poppet & valve spring.

Pump vs Compressor on a Zelos?

Single filter vs dual filter

My preference is the Tuxing dual.
First filter is fiber to capture most of the moisture and cool the air a bit.
2nd filter is the standard charcoal and dessicant to finish drying the air.

Both stages have drains and I never see moisture when I drain from the 2nd filter.

When I drain from the first filter it puts out a lot of moisture and I live in a low humidity environment.

I just think getting the moisture out before the main filter is an excellent method. Sure makes it all last a long time.

N/A  Painting Advice for the metal of a Crosman 114

Oil paint flows out really nice Smooth.
Give it another coat. A little more reduction for the second coat might be good but practice on something first.
An experienced painter can do small parts with a brush and it self levels to look as smooth as sprayed.
The airbrush takes a little more time cleaning up compared to turning a spray can upside down to clear the nozzle. So, I couldn't wait until Tuesday for the 2nd coat to tackle the accessories. I just finished the trigger guard, rear sight, and the heads of the screws but added the butt plate after a little sanding work. I'll do the 2nd coat on the barrel Tuesday still and by that time the stock will be finished, and it can go back together on Wednesday.

FX  FX Bottle Valve

When I last bought one, it was cheaper to buy it directly from FX USA than any of the retailers. Now that they are no more, all the retailers are probably the same price. You can try Utah Air and Cape Fear airguns first since they are the authorized repair shops.
Just saying UA is pretty much FX USA now.

I’m sorry guys I was playing with my Pinty bull pop

Well guys, I was playing with my Pinty bullpop I got me in a adapter for a moderator I was testing it when I took the silencer off. The adapter came loose and without me, knowing it I shot and everything when I’m flying does anybody know how many r rubber seals are supposed to be in the shroud from the factory?

Brocock/BRK  BRK Bantam Sniper, need a plenum?

First of all, greetings, my name is Pablo, and I hope Google Translate is doing its job well, as I'm writing to you from Argentina.

I've followed many threads here and read entire posts about the BRK Bantam Sniper rifle, looking for information or, rather, a solution to a problem I'm experiencing with my rifle. This isn't a defect, but rather a characteristic of the rifle and its design. The first thing to clarify is that my rifle came from the factory firing at 39 joules, the regulator set at 135 bar, and it fires an 18gr JSB at 846 fps.
The problem I'm encountering is that I only get 45 stable shots (5 fps spread) at a velocity between 185 and 155 bar, which I understand is unexpected for a well-known regulator like the HUMA, and for a carbon tank that can be inflated to 220 bar according to the manufacturer and has a 500cc capacity. I understand that's very few stable shots. The total count is much higher, but with a spread of up to 20 fps. I should clarify that this is one of the first bolt-action models.

Reviewing the posts I've read here, some colleagues have played around with the hammer spring and pressure settings on the HUMA regulator, but without good results.
My conclusion at this point is that the lack of a plenum means that, at the moment of firing, there isn't enough regulated air available, and the regulator, with that pressure drop, lets air in at the same pressure as the tank, causing the shots to have a significant spread. This is most noticeable when the tank is between 225 and 185 bar pressure. After 185 bar, the subsequent shots stabilize somewhat, but still with some spread.

I've considered raising the regulator setting from 135 bar to 145 bar and reducing the hammer blow to see if that helps, but what I'd be most interested in is adding a plenum. Has anyone done this? Is it possible?

Athlon Ares BTR G3

The Ares ETR is a 3-18x50, and yes 34mm tube, but not super heavy.

The Ares BTR G3 is a 2.5-15x50 has a 30mm tube.

Too me the turrets are superior in the G3 BTR if comparing both. IQ goes to the ETR.

Cavedweller told me he thought the reticle was thicker in his newer Ares ETR 3-18 than in his BTR 2.5-15 which surprised me because that isn't stated in the specs. I wish he'd come over to AZ to show me, lol. I might even buy him dinner.
Athlons BTR and ETR lineups really are quality scopes! Cavedwelller might have expensive food tastes...😂👍

How Airgun Slugs Changed the Game Forever

The Evolution of Airgun Slugs​

When you look at where the airgun industry is today — shooters pushing accurate shots past 700 yards, competitions being won with high-BC projectiles, and manufacturers building barrels specifically for slugs — it’s hard to believe how far things have come in just a few decades. The newest Corbin slug just took 1st place in an Extreme long-range competition with firearms!

From Pellets to Hollow Points​

For much of airgun history, the diabolo pellet reigned supreme. Lightweight, easy to make, and great for short-range accuracy. But diabolo pellets lose energy quickly, and long-range shooters started looking for something better. That led to the first experiments with hollow points and heavier shapes — great for hunting but still limited in consistency.

The Rise of the Modern Slug​

The real breakthrough came with swaged slugs — projectiles formed under pressure rather than cast in molds. This allowed for true bullet-like shapes with higher ballistic coefficients (BCs), offering flatter trajectories and more retained energy. As PCP rifles grew more powerful, they could stabilize these heavier slugs and stretch airgun ranges beyond what was once thought possible. Corbin created the FX Hybrid style slug well over a decade ago!

Competition Changes the Game​

Nothing drives innovation like competition. Events like the Rocky Mountain Airgun Challenge proved that slugs could dominate at long range, with shooters hitting targets well beyond 150 yards. These competitions didn’t just create winners; they shaped the future of slug design. Every small improvement in uniformity, BC, and accuracy filtered down into the products everyday shooters could buy. These were all production slugs as well, right off Corbins high speed production line!

Corbin’s Role in the Evolution​

Behind the scenes, Corbin Manufacturing played a huge role in this evolution. Many of the first respected PCP slug manufacturers started on Corbin presses and dies. From hand tools to fully automated hydraulic systems, Corbin’s tooling provided the precision needed to make slugs that could compete — and win. In fact, many sponsored shooters forgoe their sponsored ammo for competitions and use Corbin swaged slugs when competing at the highest level.

Where We Are Today​

Now, slugs are no longer “experimental.” They’re a core part of the airgun industry, with companies designing barrels, magazines, and entire rifles around them. And yet, the story is still unfolding. Ballistic science, barrel design, and shooter feedback continue to push slug performance to new levels. Corbin has been working with some of you, the best in the industry, Applied Ballistics and countless others to elevate the impact. Thanks for being a part of this team!

💬 Let’s Talk
  • Have you switched from pellets to slugs yet?
  • What design changes made the biggest difference for your shooting?
  • Where do you think slug design will go in the next 5–10 years?
  • What design changes/applications should we focus on?
To me, slugs in airguns appear to be where PBs were in the 70s. Benchrest and Long Range were driving factors. Back then, I subscribed to Precision Shooting and read them cover-to-cover. Everybody was experimenting with higher and higher BC bullets, faster and faster twist rates, etc.

Slugs and Airguns are in the midst of a revolution in technology. Better airguns, better projectiles, better tech, better materials; they push each other.

Of course, money is the ultimate driver. Competition with cash prizes will always push technology furthest/fastest.

Humans have been experimenting with projectiles for a very long time. I have examples of stuff like two-piece slugs (hard nose, soft tail, etc.). The fun part (well, I think it's fun) is that much of the previous experimentation has been velocity forward....limited by materials and human factors (safe pressures/weight/form factors). For airguns, the goal is less about velocities (though that's still there) and more about precision within the current subsonic restraints.

As we move out to longer ranges, BC becomes a significant driver, esp. at subsonic velocities. For out to, say, 50m, pellets will likely remain the biggest form factor. It would take a massive change in BC to knock the diabolo pellet off of its podium at short range. Maybe that will happen...

While I haven't been shooting PCP for very long, I've been watching the slugfest. Obviously, PB projectile tech is finally moving into to airguns in a big way. I have an increasing variety of .25 cal slugs in my pocket to test but my learning curve is still on the steep side with just the rifle. My plan is to get tethered and start testing slugs in earnest.

  • Have you switched from pellets to slugs yet?
I don't think "switched" is appropriate. I'll keep shooting pellets at short range until I find that there is a slug that outperforms them.
  • What design changes made the biggest difference for your shooting?
Not enough testing on my end. I suspect higher and higher BC will be the driver.
  • Where do you think slug design will go in the next 5–10 years?
I think the catchphrase will be "VLD" (very low drag). Acceleration drives the nose profile on any pure lead slug. I don't think we've explored the truly high BC form factors. (that I know of). As I mentioned before, I have projectiles which are two-piece to allow stiffer alloys in the pointy nose profile area and pure lead for the bases (those were actually for muzzle-loaders). The lower acceleration curve (lack of obduration) of airguns should allow VLD style nose profiles. OTOH, at subsonic velocities, VLD needles may not be necessary. Getting that last 0.0001 of BC is still going to drive design.
  • What design changes/applications should we focus on?
Corbin equipment has always been prohibitively expensive for the hobbyist (IMHO). I took a hard look at your stuff when I was active in BPCRS and NRA Long Range BP Target Rifle. It was always cheaper to get a custom mold cut. I'm looking forward to seeing the new press that is coming out specific for airgun. My own preference is .25cal. Much like the PBs, I think the Benchrest and Long Range shooters will eventually find that the optimum is between 6 and 6.5mm. Hunting, of course is a very different game.
