[QUOTE="MagnumManiac, post: 3076174, member: 10755"] Sectional density is a great indicator of penetration, yet, it does not take bullet construction into consideration. This is what I alluded to earlier. For example, all .338” 250g bullets have a SD of .313, but the construction of said bullets will change the amount of penetration. If we take this and compare with a .375” 250g bullet SD of .254, the outcome will favour the .338”, yet bullet construction can, and does trump this. Even if we step up to a heavier bullet in the .375”, like a 270g, it is uncertain that it’s SD of .274 is going to do much over the .338”, if we compare a bonded bullet of the same construction. Cheers. [/QUOTE]
