There was a study done on KIK powder that was published in Muzzle Blasts about three years ago. Never actually read it. ,may have to try to dig that one out.
Other than a couple pounds of Curtis and Harvey when I first started, I have never used anything but Goex. I did try Pyrodex once still have 80% of it. and bought a container of trip 7 that has never been opened.
i shot 13 round of the powder and after my frist 4 shots i up the powder 5grs because i was shooting a little low after that i was on target the cleaning was easy it is easier to clean then coex but all and all not to bad but i will stick with coex and i hooked up with a guy going to Va next month told me a price on 25lbs and i order it
