Tequila Gun PCP

The next week I will have the pieces in Texas ready to be assemble.

Awesome! You did it — after years of hard work you brought the project to completion! 👍🏼
Well done! 😊


1️⃣ For a long time I had in my heart a longing for a long range precision pistol (field rested).
But after the Ataman AP16 was swallowed up by the Russian war, I now have to ask myself:
What will replace the 🥃 Russian Wodka....? 🤔


2️⃣ So far my long range pistol has been a Chinese Artemis/SPA single shot. The PP700S-A.
However, I'm quite sure the machining and the materials of the Mexican Tequila are far superior to the 🍷Chinese Rice Wine!! 😆
And I can take 10 shots of Tequila (in .22), whereas the Rice Wine is just one lame glass at the time.


3️⃣ So, I want quality. And being German, I should know that the German Weihrauch HW44 will deliver that.
However, I don't like German beer (or any other), it's just too bitter for me. Just like the HW44 has too few shots in its tank (50cc at only 200bar!).
So, the Mexican Tequila (with 64cc at 310bar!) clearly beats the lederhosen off the 🍺 German beer.


4️⃣ Where am I going to get a thousand bucks to buy one, though....?
Maybe stop drinking...? 🤔




Prost! 😜
Or whatever you say when you drink 🍹 Tequila.

I have another kraut friend that doesn't drink Bier, as a note I'm a mix of Scottish and Austrian/German, I've got zero issue with drinking, or perhaps that is an issue, can't remember. Looking forward to a shot of Tequila, in the interest of Mexican/American relations of course.
 
Thanks for those numbers! 👍🏼
They put meat on the plate of decision making. 👍🏼


🟠 So, let me interpret and summarize —
within my own parameters —
and in the units of measure common on AGN: FPE and fps —
in order of lowest to highest power:

Presupposition Air Pressure:
My doll-house compressor only gets up to 300bar = 4350psi.
So, I'll need to take off the first seven shots.

Presupposition MV Extreme Spread:
I have decided that in a close to midrange pistol I can live with a shot velocity variation of 35fps over the shot string. That means:


🔘 Chart 1: 13.5FPE Tune
highest value: 199 m/s = 653fps
(Calc.: 653 — 35fps cut-off = 618fps = 188 m/s)
➔ All but shot No. 60 are within this bracket (653—618fps).
So, with a tune of 12.7—14.2FPE, I get 52 shots from a 300bar reservoir.
(Calc.: 60 — 7 — 1 = 52)

🔘 Chart 3: 15.3FPE Tune
highest MV: 212 m/s = 696fps
lowest MV cut off for me: 651fps
(Calc.: 696 — 35 = 661fps = 202 m/s)
➔ Up and including shot no. 38 are within that bracket.
So, with a tune of 14.5—16.1FPE, I get 31 shots from a 300bar reservoir.
(Calc.: 38 — 7 = 31)


🔘 Chart 2: 16.5FPE Tune
highest MV: 221 m/s = 725fps
lowest MV cut off for me: 690fps
(Calc.: 725 — 35 = 690fps = 210 m/s)
➔ Shot 1—32 are within that bracket.
So, with a tune of 15.9—17.5FPE, I get 25 shots from a 300bar reservoir.
(Calc.: 32 — 7 = 25)


Presupposition Test Projectile:
I suppose a high quality PCP uses high quality projectiles.
And I suppose most users will use pellets rather than slugs.
Now, I went through my list of quality .22 pellets and could not find one that weighs
15 grains even
as the test projectile in the three charts. Cf. my own Pellet BC Table attached below.

➠ What was the test projectile....? 🤔


Summary
13.5FPE* ➔ 52 shots
gain 1.8FPE = loose 21 shots:
15.3FPE ➔ 31 shots
gain 1.2FPE = loose 6 shots:
16.5FPE ➔ 25 shots

*About these power levels —— just remember: Our airgun brothers in the UK shoot with less power (sub-12FPE), and they kill rabbits and pigeons at 40 yards, and do an awesome job at field target out to 55y.


What do you think? 😊

Have you or do you plan on any of your actualy shooting on video ? You did a fair amount of shooting in the above charts, did anyone video that ?
Can you setup and do a 10 minute video of you shooting your new gun. ?
I think a lot of people would be interested in seeing your beast doing its work.

I did not a video, but in the next tuning gun, I will do it to share in the forum.
