Tried 4227 in my AR platform

I finally picked up some IMR 4227 as was suggested here. I couldn't find much in the loading data for it, but I found references of 9.8-15grs. I started low 10.0gr, the bullet lobbed toward the target, I watched it go 20 of the 35 yards. I burnt up a couple of other rounds and they shot much higher than the IMR loads. The IMR loads cycled nicely, the previous load did not, one step forward.

I haven't decided yet if I am going to try 10.5 or 11gr for my next trial, any suggestions? LC 223 brass cut down, CCI small pistol primers, Sierra 220gr match king.

trying new stuff is great and I would suggest trying a different powder. 4227 is a bit too slow to be effective in my book- can be used but there are much better choices: Lilgun or H110 are very common.
