I bought the sticks this year..a switch from Pyrodex pellets from the last couple. As Mark Wiz indicated, the sticks are slightly over bore, but that doesn't make them any harder to get down the barrel. I have fired many rounds on the range and found they go off instantly and consistently with 209 ignition. Accuracy is the best I've seen in my Black Knight, almost touching bullet holes at 130 yards with 348gr Powerbelts (I know thats a weird yardage, but my 36" leg paces and my friends Bushnell rangefinder disagree on what 100 yards is!) I'm not familiar with the older forms of Clean Shot, but improvements are supposedly made for this year, like finer powder for faster ignition, and the "avoid the copywrite infringement" new design.
If they perform in the field as on the range, consider me converted to sticks.
