No 30.06 experience with Staball 6.5 but have done quite a bit recently with .375 H&H for which it works very well in my very fussy rifle.
Two relevent comments I would make.
1) The anti copper fouling is VERY good I found. My .375 H&H fouls quite easily in the central area of the bore with many powders. Usually cleaned out after about 50 rounds. After shooting about 100 Staball 6.5 rounds all I can see by borescoping is one small streak along the central bore. Nothing anywhere else.
2) Pour the stuff slowly and steadily from the container into a powder hopper or trickler. The tiny kernels seem to fly really easily. First couple of times I used it I found many stray kernels on my bench and even on the concrete floor. I don't handle powders carelessly so this surprised me and now I am extra careful with Staball 6.5
Hope you get great results in the 30.06 That was probably my next calibre to try.
