[QUOTE="Calvin45, post: 2739950, member: 109862"] Because it’s a smaller bore diameter. “Need” is a funny word…but all things being equal, from equal length barrels with equal capacity cases the one with the larger diameter bullet is more efficient. Generates more power. And wouldn’t require as long a barrel to realize it’s full potential becuase the total cubic volume for powder to burn and gas to expand is is much greater. Extreme example but think 257 wby vs 458 win mag. Both based on a 30-06 length h&h case. Which one is more efficient as in powerful per grain of powder burned? Which one do you think would really benefit from a 26+ inch barrel more than the other? [/QUOTE]
