Huben Huben GK1 not precise at all. What I am doing wrong?

Results after the fix.
-10m target.
Not great by any means considering I'm using a tripod, but at least there is no longer totally off impacts and I was using light crappy pellets, so maybe there is room to improve, at least now the pistol is ''usable''.

First group are penetrating the playwood so I tweaked down the power+ adjust a little the windage so pellets neither bounce back or mess with my wall, no changes in group.

Those are pp800 results just for comparing, no tripod, offhand, not good either as it's a cheap ass bare minimum pcp pistol, but better.

@Savagefox It could be that you could use some practice. I could see if it was just one pistol , but now you’re complaining about another.

How often do you shoot air pistols? What’s your shooting background with pistols m? How many years have you consistently been shooting air pistols? I you an expert air pistol shooter? What sort of training do you have? Do you or have you ever competed as an air pistol shooter? If so, how did you fare in competition?

I also see that you’re taking guns apart, or at least you disassembled the GK1. Are you examining the bores? Do you have a borescope?

I've been a bodyguard and have firearms background experience, nothing precision like, but I trained a lot both in reactive and precision shooting.

I complain because I have far better results with a cheap 50 bucks beeman p17 (practically pellet on pellet) than those show on the pictures, and after getting used to the pp800 I can't group better than that, so maybe it's pistols limits. The GK1 is another history, on the test I was using tripod + rest bag so it's totally on the pistol, not me.

@Savagefox A tripod isn’t the most sturdy rest in my experience. I say that because I was able to see what my GK1 could do once I locked the gun down in a more stable rest situated on a table. I struggled until I did that. Then I was able to start working on my technique with help from another member. I’m pretty much a beginner again with air pistols. Have you tried locking your GK1 down and placing it on a solid surface? Here’s what I did using advice from @Nomadic Pirate 66. That’s with the stock iron sights.

This was the result at 25 yards. The table isn’t the most stable but it was good enough to let me see what the GK1 was capable of. Before that my targets looked like a shotgun target.

How often do you practice shooting? Perhaps you can use some work on your shooting technique as well. I had to seek out help there too. Even with the advice, I have to consistently practice to improve. For me shooting air pistols is very different from shooting air rifles. I hope some of this helps you to narrow down and pinpoint your issues.

Not to boast, but I was pretty good at the shooting range back in the day and I do far better with the P17, maybe shape. weight etc.. tripod eliminates that and SHOULD give better results. I know some GK1 seem really accurate, but mine isn't. From the start the barrel was very displaced in windage, mag chambers are irregular and don't even align on the same spot, thats why I have to dremel a inverted crown on the entrance of the barrel and that makes at least the gun usable, yet not very precise.

I guess it's because it was a V1 and one of the first units, but I read many other similar problems with misaligned treads and not top grade quality and accuracy from other owners, so if you have been blessed with a good GK1 unit, good for you, mine is not.

@Savagefox I was better at a number of things back in the day. I’ve been athletic most of my life and was into combat sports. If I jump in a ring right now and don’t end an opponent quickly, I’d likely get pummeled by a skilled opponent because I’m not in shape to compete any more. When I was young I’ve seen old fighters come into the gym off the street and it happened to them and not because they didn’t know what they were doing. They were just out of fight shape, what one might call “rusty.” Point being if you try to rely upon what you used to be able to do, you may be disappointed. If you aren’t shooting frequently, you have to work your way back up to proficiency by practicing consistently. I have to do the same with rifles. If I don’t shoot often my performance suffers.

As for the Huben, inconsistency in mag chamber diameters appears to be an issue with them. I deal with that with my K1. Even still, I have put down a decent amount of animals with it. My Hubens function well, but I really had to take some time just getting used to them. It took me over a year to get into my K1. If you really think you may have a barrel issue investigate it if you can. I suggested that you use a bore scope and take a good look at the rifling. Also examine the barrel crown. Let us know what you find. These guns can have flaws, but humans are consistently flawed. We can correct mechanical flaws.

In regards to tripods, I’m of the opinion that very few can achieve the stability of a solid table. If you lock the gun down like I did, you can lightly pull the trigger so you don’t disturb the gun’s position. You don’t have to aim. Just get on paper and see how the shots group. Then sight it in. My was shooting way off before I sighted it in with iron sights. I adjusted windage and elevation.

Look at the target above. Notice I hade to walk my shots to the right? Also look at the holes towards the bottom. That’s where I was originally hitting before I locked the gun down.



I also had to rush someone to the hospital for a medical emergency that occurred in the middle of my shooting session so I wasn’t able to take the time I needed to get it all worked out that day. Eventually I got it worked out with iron sights. Now I have a reflex sight on it.
