Powder that works well in heavy (77gr) 5.56 and 6.5 Grendel?

I was testing CFE-223 with 69gr smk but kept getting flyers

Carbon Fouling Extreme 223 is a pretty dirty powder too.

I also use CFE (although not as much carbon fouling as some others, even suppressed) and have tried AR-Comp. Liked CFE much better. I also like TAC for my 77gr .223 loads but have not tried it in the Grendel.

One thing about CFE is the original load data was very, very conservative and when loaded to the "max" was not particularly accurate. Once you get into the higher velocity node the flyers go away and the groups tighten up.

Well ****. I totally misread THIS title...

Ahh hell. Solar Rain works very nicely...

Prismatic Powders sells it I think. It is right along with their black chrome, bonded black chrome and their black chrome II...

Tac and blc2 work well in both for me, however neither would be my go to for 223, but they will get the job done. In the grendel i had much success with tac and berger 120 btts
