Q:

Length of Barrel//Length of Gun-Shroud too

I was getting used to my rebuilt Talon from Anthony226. He made me a very nice 21″ .22 cal lothar walther barrel and rebuilt the valves and jewelled it up and rebuilt my hammer too. he also placed a cool Recoil pad on my tank. And he did a great job.
Now I shot this gun Talon SS .177 cal stock out of the box and picked up on it’s characteristics quite well. It shot superb. And after Anthony’s mod I noticed the gun seemed different. My accuracy seemed less consistant.
Sometimes I would notice the .22 Cal Pellet drift on up as if it was a curve from a Baseball players pitch?! Never seen this or noticed this before. So I thought hum…. 🙄 Maybe it is the .22 cal compared to the .177? I always liked the speed of the .177 before. I used to never like a .177 until I bought this Talon SS. Nice N fast. So I thought man I want to try that barrel again. So I easly changed my nice Custom Barrel back to the 12″ stock barrel that came with it. it was also real cool of Mr.266 to polish and clean the breach end of that stock barrel because he knew I would want to shoot it again from the way I talked. So with ease I had removed the new barrel and inserted the stock 12″ .177 barrel. Now lets try it… I went into the house and cocked it and dry fired it to hear the noise because I didn’t want to pop it outside. I have very close neighbors. Man it banged loud! Almost as loud as my 22 rugar 1022! And from inside my house the dog barked next door! Then I carefully slipped that shroud on and even with the stock barrel and no work on those barrel baffles the only sound I got was the click of the gun!! Amazing. So lets see what this will do now… So from about 10 yards I was playing with my scope and I got it dialed in and bulls eye I hit a my mark. Next shot…it looked or acted like a curve from a baseball players pitch!… High ball.. next it drifted to the left a tad. Next shot it went through the same hole to the left. Next it went to a hole to the right of my mark… 😯
Batter walk…. 👿
What I think is happening here is my movements are the same as before but they have more affect on the pellet now with the shroud? The movements I make seem to effect the pellets travel before it leaves the muzzle of the shroud. I think this is whats happening?
Is this comon knowledge or am I an idoit that did too much organics in the 70’s? 8) This also rang a bell when this sniper in the marine corp onboard my ship back in 93 told me that they didn’t use shrouds because it would affect accruacy.
So even though the barrel is shorter or longer the overall gun is longer so could this activity be caused by my movement? Anthony sent me a paper group from his testing with the .22 barrel and it was a 5 shot group and it was in a dime at 37 yards. Less than a dime!
Am I incorrect ot does it seem correct? Has anyone else noticed a difference in their rifles with added shrouds like I am describing?

On the BSA you can have it gas ram installed…
Hum..I need to learn more about Springers. Im not really a Springer guy but this little rifle looks like a DragonFlySlaying machine to me 😆

Thanks for the insight on the Air tank pressure curve.
Things are making more sense to me now. Nothing but good things have happened to me since I hooked up with Mr.266 and guys like yourself with this Airgun bug.
It was Anthony who pointed me to Arizona Air and Pomona air guns.
Those guys have hooked me up. And who was it that rebuilt my Talon making it mega stealthed and tighter inside? …
This is a happening place.

So…whats a Gas ram compared to what they have in it now?

Unregulated Curve eh?…
So does this mean that the higher dollar PCP’s have some kind of Regulated tank and it is a better shooting rifle in it’s design for a regulated air flow or something? For accruacy?

First I would love to have a TX200 or a XL lighting springer. On the BSA you can have it gas ram installed if you want to in the future.

As for the power curve. A few airguns have a regualtors but mainly those for target shooting and one of the Rapids does I believe also. Many people hate having a reg in their airgun because regulators have a reputation of breaking at the most inopportune time.

We learn how to use the power curve and simply fill to a pressure at the top of the curve or fill to 3000 and adjust our aim a bit. Not really a big problem and is seen in most PCP.

Hey Adam,..
Pyrimyd dropped the ball once again on my TX-200 so I told them to cancle the order. 8)
After that I consulted with Arizona Air guns and told em what I wanted via email and that guy suggested a BSA Lightning XL. he said it was the most quiet springer they ever have offered.
So after looking at it I said hell yeah. They were the ones who turned me on to Center Point Optics to begin with.
So I ordered that BSA Lightning XL and I am going to put a Center Point 3X12 44mm on it.

😉
Thanks for all your help guy.

Then so agter about 30 or 20 shots the tank drops and it moves on us in a way that screws it up?

Ha Ha…
What the fuck is that other guy talking about 😆
Thats funny.. I think he was trying to out drink my Squirrel.

Thanks dragon, you handed me ,my ass!!

Hum… they all seem to vary all over a bit.
So this is normal for the Talons or is this normal in many PCP’s?
I see the pressure changes but I wonder what the grouping is like? Does it move too?
Maybe Im not a Tard 😀

All unregulated PCP have a velocity bell curve. Take a look at the fill pressures on that chart and then the velocity. You can start to figure out at what PSI you gun will shoot at.

Actually, I wish I had a squirril like that . peace out tz

Im sorry, I was wrong to say anything , tz

I was had! And I’m to tired to play the game. Goodnight john boy! Tomorrows another day! See you then ! ,tz

HA HA! your smarter than me LOL (no ?) sorry, ” I ” was confused! see u tz

Thats right! Don’t even try to fill obove 2600 untill you learn you weapon (Ah airgun) where the hell are you? I’ll show you what I mean

Hum… they all seem to vary all over a bit.

It’s all good brother man 8)
Keep in touch.

One basic thing I noticed too is when I charge the tank to 3000 the pellets hit the fence and stick without as much heat. In other words they seem to be moving slower and they are not as accruate. But then after enough shots and the tanks pressure drops about 2900 to 2700 it seems like it is moving faster and much more accruate.

I haven’t joined my squirrel for a drink but now that you mention it,..that sounds like it’s tiem to reach for that beach wood age taste 😆

Take a look at this graph and it will explain what your seeing.
