I used KIK up until this latest new batch of powder. I was going to order some more but managed to score 25 lbs. of GOEX 3F for $9.00 a pound so couldn't pass it up.
I found that both the 2F and 3F is a little hotter than GOEX and burns a little cleaner. Not much but it is noticeable. The KIK 2F is close to GOEX 3F. The KIK 3F is a little hotter than GOEX 3F but I did not need to change my loads in my .32 and .36. The kept close to the same POI and group size. With the anemic loads I shoot in my pistols, I could tell no difference.
I was using 2F KIK in my .50 and above rifles. I have found I had to reduce the KIK 2F loads by about 5 grains to get the same POI with the GOEX 3F. Group size stayed the same. I don't feel I get a decent group from a rifle if I cannot bench it at 50 yards and have all five touching.
