My favorite 221 FB powder. Shooting 40 gr Nosler Ballistic Tips and 20.8 gr CFE BLK. Hodgdon data shows good velocity and relatively low pressure for this max load. Accuracy has been in the high 0.2's to the low 0.3's. Accuracy improved as I increased powder charge to the Hodgdon max. Try some. I believe it will leave you smiling.Wondering if anyone has tried CFE BLK powder in the 221 fireball. It looks like it could have some merit in this size case.
