I am having déjà vu:

Benjamin - Benjamin marauder .25 power tune

Anybody know how much fpe a marauder .25 will have with a stock .22 mrod valve modded taking return spring out and end cap and using a 18lb heavy hammer spring with stock ports and hammer adjustment and air flow screw maxed out I plan on using Benjamin 28 grain dome pellets would like to push...

Benjamin - Marauder .22 slugs

What's the most accurate slugs for a .22 marauder currently I'm power tuning mine taking the return spring and end Cap out the valve and maxing out the hammer and spring and vms screw

www.airgunnation.com

Do you have a .25 or a .22? The tuning for power is not going to be significantly different. Most people, at least for me, do not shoot slugs because the Marauder barrels are choked and just do not group with slugs, none I have found anyways. At any power level.

Mine is a .22

I bought a .25 RPB barrel for my first generaton Prophet Performance. I did not slug the barrel, but did buy several brands and types of slugs and the .249 29.5 gr NSA slugs do load easier and so far have proven to be more accurate and consistant, so I think that kind of goes along with you measurements.

High pressure side has a check ball (very small) that keeps the air from entering plenum. The piston has a probe that pushes the check open via spring pressure. As plenum fills, pressure counteracts the spring. This pushes piston probe back away from check ball.

At this point, the oring can extrude and basically lock the piston in place. As pressure in the plenum drops (from shooting), the spring cannot push the piston back to open the check, creating the locked regulator.

Hth,

You were right - that split o ring was causing it to turn slow! Took a risk and kept cranking- came off just fine!

Yeah easy fix

Got it sorted with .452mm! Thanks all!

I have that brass adapter joewr. And the pistol looks like shambozzie's. Bandito.

And if ya just gotta go shoot somethin’ (and ya know ya do..) find your way up to Tulsa and try on some of them Okies for an AAFTA style match on July 13th AND one week later (July 20th) Oklahoma City will be hosting their XFT match.
Ya’all ain’t skerd are ya?

Here ya go.

It doesn't get much better ! A good gun in the right hands ! Well done especially using the different pellets

Is that the right order to connect the filters? Compressor-->desiccant filter-->coalescing filter-->dive bottle/gun cylinder.

I thought to put the coalescing filter first, to get more/ longer use out of the desiccant.

Click to expand...

I was not talking about the order of using filters, but of the choice of only two paths that would be certain to prevent condensation from occurring in reservoirs: either 1) a desiccant filter to adsorb the water vapor, or 2) a chiller to cool the air charge below ambient with a coalescing filter as part of the set up.

That said, using a coalescing filter before a desiccant it a very good idea, because it should help it last longer - of course the trade off is more "wasted" compressed air that evenetually gets vented rather than used. An even better idea would be to put that coalescing filter in a bucket of ice water to further cool and condense even more water vapor into liquid before the desiccant does its thing . . .

@Hamdanali89 : You should not be posting a slug press in this thread about pellet swaging. 1) it's completely off-topic to the pellet die application and 2) you're obviously hawking equipment for some reason. Go start your own thread if you are compelled to spam the forum.

He isn't hawking equipment. Been following precision slug press and this guy is just a customer giving his experience and feedback with the press. He posted on the wrong thread probably because he saw the name "Thor" and was just giving a comparison and feedback with the press. His English might be rough so cut him some slack

Thanks all! I’ll give those a shot

Yes that foster has a small screw with an O ring. If the screw is too tight it smashes the O ring and it won’t take air. If you unscrew the assy from the end of the air tube with the foster still attached, you’ll see the very small screw. Back it out very slightly. It may take several tries to get it right. Of course degass the rifle before unscrewing the end of the tube.

I don't know how much I spent, but I would guess about $700-$800 for everything. At the time I purchased the Yong Heng, the availability of other compressors was much more limited. I don't remember when the Tuxing 032 was released, but I know that when I was looking to buy the compressor initially, it didn't come up in any of my searches.

Supply chain shortages have been a major bummer…

So apparently I posted this in the wrong place. Anyhoo, I answered my own question. They shoot just fine, forward or backwards.

I just came across this 65mm Wika gauge that displays bar and psi at Trenier Airguns. Thought I’d post so people can find it easier.

Greetings to all, I am new to the forum. I appreciate the opportunity to share with you. My name is Javier. I currently have the Airforce Talon P and the SS. Excellent rifles in my collection are #1. I have tested them at good distances and I assure you of their effectiveness. .

Hatsan has no quality. They are really crap.

Click to expand...

And yet I have several that just work as designed. Pellets in, pellets out, pests and targets dead. I did break a few things modifying them but that isn't Hatsan's fault. Amazing how after 2-3 years I haven't seen the issues whined so much about. But then most of the whiners have never owned a Hatsan or pretty much any rifle, AEA, they whine about.

Where they do fail is HEAVY.

Thanks for sharing your trials with us! That's more information and certainly more pictures of the internals than I've been able to find so far. Thanks again!

I have the heavy liner in mine Shooting hybrid at 1000 ft./s. Every shot touching. at 50.

In CO2 tanks a 'siphon tube' is inserted into the valve to pull the liquid CO2 from the bottom of the tank. Since these tanks are used upside down, it would probably have the opposite effect. To keep the firefighter from breathing in any possible moisture?

Click to expand...

You're probably talking about a dip tube to goes to the very bottom, like in a can of spray paint, right? The tube in these things only goes a couple inches, like in a propane valve. But yeah the reason is probably is still the same, to keep them from breathing moisture.

I found this video useful.

Has anyone tried the new Warne skyline pro? The minimum height is quite appealing to me. I'm wondering how it compares against an Accu-tac?

I’ll pass something along that you guys might find interesting if you don’t already know it. It may help as you try to stay out ahead of a groundhog population. I’ve hunted a couple farms for groundhogs for over 40 years. A field that has 10 mounds, a groundhogs house, for two years or so gets all the groundhogs cleaned off and mounds flattened. Eventually groundhogs will find that mound, even if we can’t tell where it was and reopen it. So once they take up residence, even under a shed, rouge grundys will eventually find the abandoned groundhog house and set up shop.

True true.

Have seen the very same thing myself over the course of 25 years in my back hayfield.
No need to leave seed stock, they shall return.

I use the ROCKSHOX 600 PSI pump Schrader adapter with teflon tape to pump up my HW90/.25. Works great, adapter cost 9 bucks:
Rockshox Monarch Air Valve Adaptor Tool
Use small metal rod to tap out pressure. For this unit, using either old DIANA MAGNUM 20grain or H&N FTT 20.06grain, i get 19.0FPE from factory setting with 60LBS cocking effort, ~18.51 FPE=20BAR with easy 40LBS cocking effort; 12.5FPE=14/15BAR with very easy cocking. BAR measurements using Rockshox High Pressure Fork & Shock Pump-
Cocking force measured with bathroom spring scale. The brass AOA Quick connect male to Schrader valve only works if I take off stock, because our Benjamin hand pump's female QC head is to big, causing interference with stock.
