New member

Hello,

I'm a new member here. I've been into air guns for a while now. I have a few nice pieces, e.g. Beeman P1 and R9. I'm looking into getting into a PCP as these new guns seem super cool and accurate. I'm looking forward to researching the knowledge base in these forums and chatting with you all.

Have a great day!
welcome... what part of the world are you living in?

STUD Loading Solutions in Action: A Day in the Life of John from Johnny Stags

I might be a professional contract shooter. No contract but several permissions. Shot a crow yesterday at 130 yards. The land owner where I shoot prairie dogs sure appreciates having a few thousand less dogs eating his alfalfa! Would it be more fun if I was paid? NAW only a bit cheaper.

N/A  30 cal options

Three excellent .30 pellet shooters in my stable, RAW, Kalibr TacII and EDgun R5. The only slug gun I have is a .30 Uragan 2, it does very well with Zan 49gr. Meet me at the range one day, you’re welcome to try them all.
ZAN's .30 slug assortment helped narrow preference of V3 and U2 (700mm) sluggers. 54 and 59 grain were tops, mainly 59. Various manufacturer offerings in 59-61.5 grain have done well, U2, with balanced valve technology, is less ammo (pellet/slug) fussy. WM

N/A  Good Sale on Airmax Springer scopes.

For the next day and half DVOR has an excellent sale on Hawke Airmax 2-7x32, 3-9x40 and 4-12x40 scopes. I already have an extra 2-7 so I ordered an extra 3-9x40 to have on hand. Prices like these are worth jumping on.

This has been a public service announcement.


Fwiw I already use a 2-7x32, five 3-9x40 and a 4-12x40 Airmax. They are probably best value in Springer scopes at regular price.

Air Venturi  Avenge-X O-Rings

I had some early leaks and then an odd failure - at about 3500-3800 lbs while filling, the burst disk on the gun blew out - this seemed to create a cascade of failures - couldn’t even begin to build pressure with my little compressor and it clearly wasn’t a single point - that prompted the first complete tear down - the reg was leaking, the axle and the bottle seat - probably more but those were the big ones - then chased little leaks until I found them all - including a scratched seat where the poppet valve sat that was very slow but was leaking - the larger ring in the regulator has gone several times but I’m shooting at 175-180 bar most of the time - Vitron rings in the reg have been holding better and haven’t failed yet- stock small compressor with the little in line filter was probably allowing at least some water in - solved that as well and the gun has been stable since - will be doing a post on a simple solution for little compressors - initially I found a lot of brittle and deformed o- rings so ended up replacing all of them - and a few mistakes along the way -
Yes, most the orings are junk. Hard and flat. Our 3 went out after about a year. Too good of a gun to not keep though and now I feel like an expert lol. Had them apart so many times. I now have tons of orings for the entire gun. The other place that leaks is the fill nipple and the air cylinder into the block. The fill nipple is the 2nd hardest one to change. I need to make a tool for that. The 1st is the poppit guide oring in the valve.

Air Arms  Air Arms TX 200 Rowan Trigger question

UPDATE: Just finished the install, as part of my winter servicing/lube. The trigger fits great, and no interference or side play issue. Once I got things adjusted per their instructions, it fit as hoped. Actually, I am quite pleased with the results. It certainly achieved my intended results and works GREAT ! I appreciate your inputs. I'm calling this one good.

Compressor Journey Over

Amazon hand pump? not for long, like 5 pistol tank fills $60

NYDWXYZ all you need if just filling a small gun tank. Noisy , slow , hot $200

Gx cs4i. Very nice , fairly quiet, slow , cool, fills 9 liter tank in one shot ( 5 hours ) $480

Tuxing TXED042 or similarly based . So far: heavy, very fast, relatively quiet, because fast will top off my 9 liter before it can get hot. $360

View attachment 528734
hi BD- are those the tall filters on your Gx4 set up ? Do they take long to fill before pressure builds ? or do you have some type of valve to keep them under pressure when disconnecting or restarting the unit Mounting set up looks good. S.

3D Printed Scope Mount's Picatinny Rail Collection (25,4mm tube scopes) (free)

I 3D print stuff and the only possible issue I see with mounts would be the stability. I cant say for sure but I feel like dimensions will change with temp and moisture. I know temp will do it and filament absorbs moisture. Air guns dont have enough recoil to be an issue but the possible stability could cause poi changes day to day. Have you checked for poi changes from temp and humidity swings?
No, I haven't checked that yet. I wouldn't use them to shoot a match either. I designed them out of curiosity whether it can work as a cheaper alternative or for the not too serious shooting work. I have an Air Venturi Avenger Bullpup that already gives a lot of poi shift problems from the factory using metal scope mounts. After placing two barrel bands, the poi shifts are largely fixed, but I still suffer from it every now and then. I am already used to the poi shifts and have learned to live with it. The first thing I usually do with a new shooting session is to immediately readjust my scope. There are so many other factors that can also influence this.

N/A  barra 250z bolt

If you remove the rear pic rail there is a silver adjustment screw underneath that houses a spring loaded ball bearing. Turning it clockwise will increase the tension on the detent hole in the closed position. I recommend using some blue locktite once you have it set where you want. Mine tends to loosen over time and I will need to locktite the next time I adjust it.
You nailed that one. Thanks.

Tuning  PCP regulator designs

As such, when you are measuring the force exerted by the stack as it is slowly compressed, the output is no where near linear, but is a sawtooth with varying peak heights and valley depths.

This is why the stack may close off flow at a slightly lower than setpoint pressure (valley) or higher (peak).
I imagine if someone recorded the sound of a regulator cycle -- like with a direct to metal high-sensitivity and high dynamic range microphone recorded at 192K samples per second and 32-bits per sample (typical digital audio workstation setup on a home computer) and worked some audio magic on it, they'd be able to isolate the sound of the piston "eeeking" past the o-rings and also isolate the sound of the belleville washers making whatever sounds they make as they get compressed. I imagine that, near the end of the cycle, the bellevilles might exhibit "ticking" sounds.

That might be a fun project for a really, really, really bored audio engineer / musician that happens to have a PCP rifle.

HW/Weihrauch  Early 80's HW35E .22 cal

On some shot strings I start to get a cloverleaf but it never lasts for all five shots.
That's exactly what happened with the 177 R7 I just did. Little glimmers of hope here and there but then hope was dashed on the rocks of reality when it threw number 4 and or 5 and >1" away at 25 yards scoped. Also changing pellet types often moved the POI 4-6" from the last type. Not sure if yours does the same.

I'm sorry yours performed as you suspected. I was hoping to hear differently.

Best of luck to you
