Hard times

Today was a very fun shoot and I beat Tony T and won my 5 bucks back I lost at the Sonoran Classic Sure was a lot of laughing and joking going on down the line....A mixture of PCP and Springers....Those of us shooting Springers are getting ready for Saturday which should be a fun time....Now it's time to grab some Advil

Whether we like it or not, it comes with the acoustic signature. It's what we hear. And yes, it's different depending on the environment.

Yes it does, but there is nothing we can do after the decompression to alter that acoustic signature. As you mention below the only time we can influence that is before decompression.

Here's the first set of bare shots with the time domain plotted in dBs. Is each pointy spike an echo? Could very well be. Why such a long tail? Is that a continuum of echos or something else? Interesting. First echo is @ 46ms delay, (~16m), next is roughly double that, could be a reflection. There's a couple of them. Then there's something distinct at 201ms delay (~69m). Using 344m/s for the speed of sound, for these calculations.

Temperature this AM was about 40 degrees. I am at sea level + 20 feet. The signature which shows up very clearly in the shots for the Tatsu at ~202ms after the uncorking are of the impact of the pellet on a cinder block 40 yards from the shooting position. It won't be in every shot. I wasn't trying to hit it. It was just yhere. The geometry is explained in the first post in this thread and includes an explanation of the timing of that spike. I didn't try to compensate much for temperature but used 1075 fps for the velocity of sound this AM (1050+temp(f)). I remember thinking when I picked the number it might be a bit low.

The uncorking event takes about 7.5 ms on most air rifles. That is the time from the pellet exiting the muzzle to the pellet getting down range a couple of meters.


Stan's Posts here are very helpful in analyzing the uncorking and decompression events.

WobblyHand said:

The moderator can't change the echos pursue, but it sure can reduce the signature of the main event, so all the echos are quieter, since the stimulus is quieter.

That is exactly correct. Almost ALL of that signal after about 7 or 8 ms is echo and harmonics in the physical structure of the gun. You can't alter it unless you alter it's source.

So lets think about what we are going to hear. First there will be the "tick" of the trigger, then springs and things decompessing and hammers smacking valves, and finally air venting down a tube pushing a plug. These things all generate harmonics in the gun. Finally (maybe 12 ms, 10 on a gun with a FAST lock time) we hear the uncorking even before there is much if any air exiting the moderator. All of these things are apparent in Stan';s posts. Then the pellet exits the moderator and a blast of air follows it in less than a millisecond. Uncorking is over and decompression begins. You can bound decompression by locating the point where the aggregate RMS peaks and begins to decline again which appears to be about 2 ms after the pellet exits the muzzle of the moderator.

So that is what we have to work with, everything we do we have to do in that 5 to 7 ms period between muzzle exit and 2 meters down range. After that we are hearing the echos and harmonics in the gun.

lol true

the FT matches are still listed on the Range's website. Ive emailed the addy listed but no response...

thanx

did he recycle the first couple shots? or the cold sticking oring is fixed now?

I think he had already shooting his gun when he started recording

FX M3 600mm 22 cal barrel kit with pellet probe and FX mag. $225

22 cal Stud mag kit for M3. $125

Both for $320 shipped CONUS
PayPal F&F

I will NOT sell the Stud kit separately unless I’ve already sold the barrel without it.

Thanks

Ernest! Hope to see you at Northeast Airgun Classic!

I tried the tissue test no movement at all , only getting air out of the adjustment hole in the rear of the tube .
I kind of think its the hammer strike thing , might be alot about nothing .
The quest goes on .
Thanks Ray

The hammer has vent holes and exhaust out the rear adjustment hole.

That has to be one of the best looking guns I've ever seen!...no jealous or anything....

I understand completely. But if you look at it from my viewpoint, perhaps you can understand my desire for anonymity.

Hawke Optics has given me permission to release this version of ChairGun. They appear to be the copyright holders of it. And they have told me they are not aware of anybody else with any legal claim to it. None-the-less, given the state of our legal system, there is nothing saying that somebody else might not come out of the woodwork claiming I've infringed on "their" rights.

Further, I'm not a lawyer, nor do I have a legal staff. While I think the ways I have released the software are all in conformance with Oracle's licenses ... who has the legal staff that they have?

I'm trying to be a nice guy and share this work with others so I'm not the only one benefitting from it.

But I don't want any trouble from it.

No problem. If it turns out that your version of Chairgun is safe to use, then by all means I will try it.

Until it is proven/verified safe... I will leave it to others to find that out. Not worth the risk for me. Plain and simple.

In case it turns out that your "new" version of Chairgun is safe to use, I will be one of your best proponents.

Until then... there are too many red flags for me.

All my best!

Kerry

Thanks,

Yes very nice, light, handy gun and very accurate. Mine not shooting quite as hot.

I’ve got an HW30 with a Perfek trigger. If you polish the sears they break real clean. Nice gun

I don't have the 70 but I do have the cricket 2 in 60 and it's really great and accurate. I'm sure this would be like most cricket's and have same accuracy and build quality

As long as it is on amazon it does. Its great, I set it up to notify me if an item goes below my set price point

That's wicked!

@ FIdi_G., you did not mention the distance you are shooting. Wind could be a factor. A 2 mph wind will move a pellet a couple inches @ 100 yds and you can't feel it on your face.. Try wind flags and study the wind.

Check out Nrl22.org. They have all of their rules and the course of fire for each month is posted.

No longer shoot with Co2 ... agree with others once below 70* and into the 60's is about it IMO.

What is your reg pressure set at ?

Click to expand...

Not exactly sure the reg setting but I think it is at 140-ish or close to that.

Running on Mac OS 13.7.6 VENTURA-

No matter what rifle you are looking at....when your spending big bucks, it pays to try it out first, before you buy !! Looks mean nothing if the rifle is not comfortable to hold and shoot !! We are all built differently, what works for one may not for another, so....try before you buy !!!!
