2208 is good for.69gr and up from my experience. I have found around 55gr pills are best worth .bm2. 69gr 2206h above 69 I.e 75/77/80 2208. Others may have found differently but thats what worked for me (admittedly any of those powders I listed would do all projectile weights sufficiently.I just like testing etc, can't get away from my "research" tendencies )
