H&N may have a 22 pellet to fit Huben GKI

looking through all the 22 pellets and about 80% do not state the size of the pellet, On some of H&N pellets the head size is stated, I am looking for a pellet that will fit my 22 caliber GKI, Looks like I found the biggest head size pellet I could find,
Its H&N Field Trophy pellets. If anyone knows of a bigger 22 pellet please list it..
Most of the pellets that I have and have come across have a 5.50mm head size,,
  • Caliber: .22
  • Grain: 14.66
  • Head Size: 5.55mm*
  • Quantity: 250
  • Nose: Domed
  • Use: Field Target and Hunting, up to ranges of 50 yards

The AEA pellets will fit your huben just fine, they won't back out or bounce around. They are ticker skirted pellets
 
I am surprised the chambers in the cylinder are (apparently) so over-sized. Have to wonder if this was a deliberate design decision or an oversight. I haven't had an issue with any .25 pellets in my gk1. Slugs of course are not typically a good fit. I have mentioned before - NOE BBT molds produce nice snug fitting slugs for me. Both 40 and 50 grain fit in the mag nicely, 60 grain are too long (obviously?)
