I guess I have somewhat different thoughts on Kik. I put it side by side with Goex and Schuetzen...all FF on the range one day. Testing in both my .50 and .54 cal Investarms Hawkens. Although I couldn't tell much of a difference in accuracy, I could definitely tell a difference in fouling.
The Kik was by far the dirtiest, followed by Goex, and then Schuetzen. I swabbed between each shot, shooting 10 shots with each powder using the same weight within a given cal (70gr for the 50cal & 80gr for the 54cal). The swabbing patches were noticeably dirtier for the Kik....at least 50% dirtier than Goex. The Schuetzen was just a touch cleaner than Goex in my opinion.
Now I don't have a chrono, so I can't provide any feedback in the velocity area, but there's no question that Kik was dirty for me than Goex or Schuetzen.
Although Kik is maybe a couple of bucks cheaper per lb at Powder Inc than Goex or Schuetzen, I don't think I'll get it again or if I do, I'll just use it in paper punching 40gr loads for the kids at the 25 yard range.
Oh, ignition was the same for all 3 powders using a CCI mag cap; instantaneous.
Next I have to compare Schuetzen vs Olde Eynsford since they're roughly the same price.
