748 and BM1 both flow nicely and throw well,2206 is great powder and goes well in .223
take your pick and go load up and enjoy shooting...dont get all hung up on last fps......it really not that big of deal if its 3000fps or 3150fps at sub 200 yards the goat/deer/rabbit/wallaby/pig etc etc etc wont know the difference if you put projectile in right place.
