Bullet shape has a lot to do with it a hollow point has more drag than a round nose. T he ratio of length to diameter is close to the 300 while the plastic point gives it the added BC like a spire point. I can hold on the top edge of a 20inch gong at 240 yds and hit it in the mid area thats pretty flat for a MZ, I have to hold almost twice as high to hit it with a 250. Lee
