I just loaded some with that very load. Honady 55 gr sp and 38 grains of imr 4350. Winchester lr primers. Have not shot them yet just got done loading them. My old load was 35 gr of imr 4064 and it shot a little under an inch, but hoping these ones might perform a little better. Velocity isn't everything to me, accuracy is more important to me, i'm still way above a .223 rem.
