96 DB with DonnyFL Ronin at 20 yards.

@@backyardairguns omg thats still way too loud i like below 80 db

Thanks - It is really a fun pistol to shoot.

Altaros 51g 6.46 shoot really great in this pistol. I also saw where NSA make some 6.4x slugs in 25 Cal. I have not tried those, but I plan on it.

You offer up a really good question. I have not tried the test that you mention, but I will try it. I would like to know for myself. I will follow-up.

It's a great pistol. The Altaros 51g 25 cal 6.46 slugs work great. I plan to order some of the NSA 253-254 slugs and try them. I would not use 6.35 slugs because they jam.

Very good point point and observation. i will try your bag idea.

Part 3 got edited before Part 2. I know it's confusing. I plan to get Part 2 (Pellet Accuracy) out soon.

You too Amado!

It's not too bad. But without it, it's crazy loud.

@ I have 5 or 6 moderator for my gk1…. Yoko is gonna be my last one… quietest so far is the hugget sniper

I appreciate it David!

I'm not sure on the 22 Cal.

You will love this PCP pistol!

They were NSA .300 in 61.5g.

I'm still editing Part 2. Part 2 focuses on pellet accuracy using JBS, JTS, and AEA pellets.

Great, pretty anxious to see. Thanks for sharing!

Thanks Kurt. I have at least two more videos coming on the GK1.

The Speed Loaders works really well on this pistol. As for weight... yes, you can use lighter pellets and turn the power down to get more shots. I like the power. :-)

What up Lead! :-)

@@backyardairguns hey Mike 🙌🏻, such a great idea for magazine speed loading you had , if I get a gk1 I will definitely buy a magazine speed loader man 👍

My Huben GK1 25 caliber I was able to punch through a 2x4 with 34 gr JSB and heavier slugs. I also shot through two 1" pine boards with the H&N hornet. This PCP is amazing. Have a good day everyone.

@@jessicasmith957 I have the slug mold from Gregor at home so I re-use all the lead I can find in the trap. Some are slugs are 48 grains, others are 51 grains and they all fly like a laser at 50 meters. This is an awesome little 'tool', but as soon as they start to leak mweehhh it becomes problematic especially when they leak so slow that you only see it when you wait 24 hours.

Agree - This thing Thumps

We love noobies. I have several more videos coming out on what this pistol like to shoot. Because it is not regulated, every shot will drop in fps and fpe. so you will never get a consistent shot string from this pistol. However, it still shoots accurate at falling speeds. For example, I can shoot 17 rounds, which is what the magazine hold, and all of them be very accurate. I shoot the heavier 34g pellets from AEA, JTS, and JSB. I have a slug video coming out for the GK1. The GK1 is very slug picky.

Thanks

I have a entire video on shooting slugs in the GK1. Altaros is the only slug I found that does not jam this pistol. The GK1 is extremely slug picky. The slugs need to be 6.46 in diameter to cycle correctly. Altaros makes 6.46 slugs in 25 cal and they shoot amazing in the GK1.

@backyardairguns please post part 2! Cant wait to see what 50 grain can do!

He is da man!

​@@backyardairguns yes sir he is. One thing i appreciate about my K1 and GK1 among many, is the fact if i break it or it just goes south on me i have a place to get it taken care of. Kelly is greatly appreciated by me. Have a good one brother. David

Kelly is the real deal dude!!! Can’t wait to get one from him

I have the AEA 50 MAX and T9 357 pistol on my list to acquire and do a review on.

That's no comparison. The Rex is a single shot and the AEA Max pistol is a bolt action. Also, both are not really pistol sized especially the Max. You can empty the GK1 (17 rounds) in a few seconds. Other brands have still a long way to go before they can match the GK1. The Bintac T9 is a nice semi auto alternative, but hardly a pistol.

@jbhk7977 he said most powerful pistol. It's not. These are also air pistols, pretty comparable

The 109 db is at the muzzle. It falls to 94 db 20 yards away in my backyard, and in the 80s one backyard over.

@@backyardairguns still and barra 250z without moderator its 91 db right next to me and its still super loud to me so i had to put buck rail moderator ( $40 ) and it dropped to 80 db and you have no idea how much quieter and its finally back yard friendly

No way to get that much air power out of a short barrel and have it be very quiet.

This pistol will shoot 80 fpe using slugs. I have the slug video on the GK1 coming soon.

@@backyardairguns thats sickkkkk but i wished they were regulated and still be able to shoot 80 fpe for minimum 1 full mag then i will buy it!!!!!

Thanks Eitan. I have two more videos coming out this GK1. One on the best slug to use, and another on pellet accuracy. This pistol is really fun to shoot.

@ I like to remind myself that I’m a prepper first, an air gun enthusiast second. This p.c.p. checks both boxes. It’s powerful, accurate, well built and Huben makes a 5000 p.s.i. hand pump that could fill it in a bug out scenario; let alone the fine quality options available to convert it into a pistol/carbine.

@@eitangrinspon1637 All good points - I have a Power Test video coming soon on this pistol and it demonstrates what 80 fpe can do. 🙂

@@backyardairguns Looking forward to it very much. I’m also interested in figuring out the best slug weight, in case I want all 17 available shots (38 grain?).

@@eitangrinspon1637 This thing is extremely slug picky. You need to run slugs that have 6.46 diameter. Most slugs in 25 cal have a 6.35 diameter and they slide in the chamber and cause the pistol to jam. The best (and only so far) slug that works great in the GK1 is the Altaros ATP Smooth Slug in 50 or 51g that are 6.46 diameter. I have a video explaining this coming soon.

I'm used to doing reviews on rifles. :-)

94

@ not on high power tho right.. maybe 2 turns in

That was on high power (10 Turns) and 20 yards from the pistol.

I can’t get ten turns out my gk1 only 3

@@Tom-jw1pe My bad. I was filming a review on the AEA Gen2 and the hammer spring takes 13 turns to go to full power. The GK1 will only turn 3.25 times. I had it maxed out at 3+ turns.

Hi Colin - I make and sell those rails. I use them on all my AEA Challenger Pro and Challenger Elite rifles. Go to my website at www.backyardairguns.com

I think 60g slugs would shoot better in the 30 cal Long Barrel because the speed (fps) will be higher.

@backyardairguns ok, however out of 24" generation 1 70 gr can be the best?

Hi Antonino - I think 60g slugs would shoot better than 70g slugs from the Challenger Pro 30 Cal because they would go faster. I think 70g is too heavy for 30 cal short barrel Challenger Pro.

I have the heavy hammer spring installed and the Reg is set to 200 Bar.

Wow. That’s pushing it :)

I don't have an original Challenger SL in 357 Cal. I know they will single load into the Challenger PRO 357 and the Challenger Elite 357.

Thanks Bonita! :-)

This rifle will let you quickly swap barrels. I will get the .58 caliber barrel when it comes out and test it.

@@backyardairguns Thank you so much bro, I look forward to seeing you test the .58 caliber👍

I'm capped at 30 yards in my backyard. Thanks for the heads up on the JSB 18g.

@ no problem it’s kinda insane that the notos can shoot at 50 yards considering the barrel I so short

This rifle was doing 600 fpe with the reg at 220 bar. Some folks have cranked the reg up and get close to 900 fpe. Based on that, the rifle has more energy than a 9mm and 45 pistol. But less energy that a .223 / 5.56 rifle.

Thanks for being a fan. The Notos is so fun to shoot! I want to get the Zelos next and test. I have some videos coming soon on the Huben GK1 PCP pistol.

Thanks :-)

Thanks Jerry. This video took me about two weeks to film and edit. :-0

Thanks Jerry. This video is one of my most viewed and it was certainly fun to make!

I appreciate that

220 fpe from a 30 Cal Challenger Pro is something I've never seen. I think you would have to open the reg all the way up (well past 200 bar) to get near to that. Sound like a challenge. 😁
