[QUOTE="358 Guy, post: 2178709, member: 60067"] A 175 gr. 7mm bullet has a S.D. of 310. A 30 caliber would need to weigh 205 grains to match the 7mm S.D.. Now assuming the bullet construction is identical, and the impact velocities are the same, which of these bullets has more potential lethality on game? The 30 caliber has more bullet weight, thus it will have more ft. lbs of energy, and it has more frontal area. If using the S.D. as the constant, the math tells us that the 30 caliber has the greater potential to produce a quick kill. [/QUOTE]
