20mm pcp airgun from finland very skilled man homemade!

What do think airgunnation and youtube people if the gun maker (20mm) shoot straight up out sky (with helium or air) and take time how long the projectile to come back to ground of course safe place! Big lake,sea or wide field when its calm when you see where its lands? Should we shout out to the gun maker if he should do that?????? I love to see that!!!!
 
I’ve been liking for the Perfect squirrel gun. Looks like that would do the job!

1550 grains weighs more than most squirrels. I hit one that kept barking at me while Groundhog hunting edge of field, 400 yard stretch. Squirrel was 10 yards above me. I used a 55 grain .22-250 V-Max. Never saw a Squirrel gutted & turned inside out at the same time.
 
That is Marko from Finland. He has made over 3000 fpe with that gun. He is shooting 158 grams/2438 gr.

Is he the same guy that posted that original fpe years ago on an extinct forum? If I remember back then that fellow used a 600 grain monolithic turned slug & a dump valve. He stated it was less than pleasant to shoot & only did it to see if he could. He wasn’t out to set any records when he beat an 06 in muzzle energy & probably terminal to a short distance with a PCP. 
If that’s the same guy he came a long way. I haven’t watched videos yet, and I’ll see if I can track down old post. I’m very curious scientifically, not like I want one, because I don’t. I’m curious if they’re the same guy. If Helium is used in either one. At what point did he decide a controlled valve & longer barrel worked better than a dump valve. You know 1st hand very well what a “measly” 1200psi can do with a .22 slug & the right length barrel. I really wish more production guns came (at additional cost of course) with optional barrel length up to 36” on .177’s-.25’s. Seems AF is only one not afraid to put a 36” barrel on a long rifle. Short bull-pups, sidelever, big multi shot mags being the in thing.
IDK. I guess short has been preferable for a long time as most guys cut their Brown Bess down to 2 barrel bands or shorter instead of production 3 band length.

It depends on the application 😉 I have both the carbine and the bazooka as my wife calls it (Texan .45lls) I love hunting with the carbine easy brush popping but if I'm hunting in a stand expecting a big bore the .45 is my go to
