I know often times we shoot what we are comfortable with. I do as well. But I have been thinking about these bullet weights in the 223 when I only care about shooting out to 400yds. I was curious if the 40gr leaving the muzzle at normal 223 velocities, 3600-3700, would drift less and shoot flatter out to 400yds than say a 50-53gr bullet travelling at around 3250-3450. At what point does the heavier pill catch the 40gr and say goodbye? If the 40gr holds its own and still anchors a coyote or cat at that range then wouldn't the 40gr be the better bullet?
