Yes I was talking exactly about this barrel-mag misaligment. But I am making pure speculation here. Its just I can't find another reason why it has such poor accuracy.

My request for help to you all was whether you advise me to talk to the store assuming that it is a warranty issue or to take it to a service center to disassemble it and look for the problem. Do you think inaccurate shooting would be accepted as a warranty issue?

Absolutely

Hi all! I have problems with my brand new Huben gk1 caliber .25 Ver 3+. It's making pretty bad groups with Discovery scope installed at 25 yards. Groups are 4-5 inches. Scope is good Discovery 4-16x44 and the mount is good quality as well. First I thought the problem is me but other more experienced shooters gave it a try and they said that it really is shooting bad. Do you think huben shop may approve this as warranty situation? After all the gun function properly its just shooting bad.

After all these vids and reviews on the net I really expected hole in hole at this distance with scope on it. And I only use JSB pellets 25 and 34 grain, no slugs no experiments..

I would try bumping up power. Is it using a magnetic speedloader gate? Maybe try removing that as well. Which version barrel adapter is being used?

Speedloader is not magnetic just standard 3d printed aftermarked one. My huben adapter and moderator arrived some days ago not yet tested. I'll try higher velocities this weekend. Thanks for input!

With my setup my Notos can do 400 fps CPHP accurately but GK1 cannot. 550 fps is good with GK1, I tend to end up at 400, 550 or 710 FPS when adjusting. Im not holding the chrony for any higher fps.

 

[Rubik777]

Way better results today. I increased the velocity 800+ FPS (25 grain JSB pellets) and this is result at 38 yards. In the middle are the first 17 shots and than 3 groups with 5 shots. Not perfect but getting there.

Get rid of the JSB pellets and start shooting JTS…..your groups will shrink even more.

I agree with longdog on the JTS pellets in the Huben platform.
I'm a huge JSB fan in all of my guns, for a very long time.
However, I found that the softer lead of the JSB's, tend to get distorted as they rotate around the fairly violent, mag indexing operation upon firing. My accuracy was OK, but not impressive.

Then trying the JTS's much harder lead composition, seemed to produce far less pellet distortion, resulting in smoother operation, and tighter groups in both my K1 & GK1, in .22 caliber.
I was surprised at the difference they made in my Huben's.
YMMV
Have fun.

Turns out my local gunsmith didn't install the barrel on my GK1 properly. It's not screwed in far enough, leaving too much space between the barrel and the magazine.

Does anyone know if it's difficult to install and align the barrel on the GK1 yourself? Do I need advanced tools for the alignment?

Seems like ya screwed the barrel in till it touched the mag then back off and 1/8th turn. I got a shorty kit for my .25 when I tried installing the barrel he sent it didn't have enough threads to install. I ended sending it back and Kelley fixed it.
