After viewing Ted's vid on pellet head size; does anyone actually make 0.22 diabolo round head pellets which are labelled 5.50 ? All I can find is 5.51+.

"Ted"As far as I know 5.51 is as small as they come. And, for what it's worth, I think my Matador preferred the "small" pellets most in that video because it had a particularly aggressive choke. Ed alluded that the R2.0 Matadors had this idiosyncrasy, and that is was "corrected" in the R2.5 and later models. Most of my .22's do best with 5.51 and 5.52. I know you know this, but I want to reiterate that the sorting exercise was not to determine the "best" pellet head diameter. I only wanted to show that finding an optimal pellet size for your (LW) barrel was necessary for achieving maximum accuracy.
Yep - I have seen this, too. I lack the skill or luck to have found such a combination for myself. But, I have personally shot such guns [belonging to others] who have. I have a few guns that got very close to doing this. But, the additional speed (950+ fps) caused an increase in fliers. The groups got tighter at 100 yards, but the fliers became more frequent and much more pronounced. If I cherry-picked my results, or kept my groups to 5 or fewer shots, it would have appeared that I owned laser gun. Some of those small groups were the best I have ever put on paper. But, 10-shot groups always brought me back down to earth, usually to the tune of 7 in one ragged hole, and 3 others barely on the 5" target. My search continues..."Wingman"
With the correct head size pellet matched to your bore you can also shoot them much faster than the norm and still keep them stable. I can shoot my 5.50mm well over 1000fps in my Matador without any noticeable change in accuracy.
