Huben Huben GK1 .177 most accurate pellets?

I'm wondering what the best pellets to try in this gun are for target accuracy at 30 yards or less, not terminal ballistics on critters? Highest velocity doesn't matter, but I would like it to be decent so that I have less problems with drop compensation. Best diameter, brand, weight? One type Hatsan Vortex pellets are sometime very loose, one move forward enough to jam the cylinder. I had to push it back into the cylinder with the CF rod.
 
I have this issue with a .25 caliber with one particular pointed pellet. Any pointed tipped pellet will do this because it doesn't come in contact with the magazine's narrowed rifling before the tip extends beyond the front of the magazine. Maybe it would be optimal to find a brand of pellet that is a bit heavier, so it is longer and has a wider skirt. That way it holds back onto the magazine instead of riding it forward.
 
So far JSB exact rs diabolo 7.33 bout 825fps seems good out to 27yrds in mine. I've shot JSB beast 16.20g, redesigns monsters 13.43g rws supermags 9.3g
Hades 10.34g, h&n hollow point 7.1g. still working what's best using the non regulated.
Just got a GK1 in .177. So, what is your best shooting pellet, up to what range, and at what velocity?
Thanks!
 
Am shooting jsb 13.43 cylinder type or FX 13.43 cylinder type shooting 700fps seem to shoot the best of most pellets I've tried.
Yes, JSB 13.43 Monsters have been the most accurate for me as well, thanks for the tip. Although not chronied, I found filling to 19.2 mpa yields about 8 consistent shots, then the group moves up about 1 moa for 5 or so more consistent shots. I am seriously considering a regulator. I would be happy with a full mag per fill. If anyone shooting a GK1 .177 has any better results, please comment, thanks!

Jsb exact 16.2gr fits good into .177cal

Jsb exact 16.2 gr, 2 full turns gets me 8 shots at 970 fps that's 33fpe
 
Let me ask this, How do the pellet's fit in the GKI 177, I am sure the 8gr are going to be loose , But how about the 10 and 13 gr pellets Any problem jamming. Do you have to seat each and every pellet??? My GKl 25 pellets H&N and the GTO fit so tight my thumb gets sore pushing in 50 to 80 pellets ,,,

So far the JSB EXACT 16.20 shooting the best in my .177
