Never got to try the ballistic tip as the 50gr v-max shot so good.Don't know the twist of my barrel.I also use IMR 3031,24.5grs.Been playing with some reduced loads using blue dot,shot a nice group at 50 yards using 9grs with 50gr v-max.Weather gets good and I'll try 9-11grs and shoot at 100yards see how they do.
