Bullet Penetration – Part 2 (This cartridge vs. that one.)

As I expected, very few of those participating in the bullet penetration poll guessed the deepest penetrating bullet. Actually, 92% were wrong. The .264 Win. Mag. 130 gr. Swift Scirocco II bullet at 1810 fps penetrated the deepest. Why, because it failed to fully expand. All bullets have a low velocity limit where they will not expand in tissue and that appears to be about 1800 fps for the Scirocco II.

Those that picked the Trophy Bonded bullet were close but it only beat out the 110 gr. TSX from the .30 Rem AR by a 1/4 inch. Why, it was going slower and expanded wider.

.308 Win. 165 gr. Trophy Bonded Bear Claw, 2700 fps

.30 Rem. AR, Barnes 110 gr. TAC-X, 2880 fps

The .243 Winchester and .30-30 Winchester loads penetrated to almost the same depth and both work wonderfully well on whitetails which, along with a lot of other tests and experience proove that level of penetration and expansion is all deer hunters need.

.30-30 Win., 170 gr. Nosler Partition, 2165 fps

Here is the actual data:

LOAD PENETRATION EXPANSION
.264 Win. Mag. 130 gr. Swift Scirocco II, 1810 fps 22.00 + 0.37
.308 Win. 165 gr. Trophy Bonded Bear Claw, 2700 fps 14.25 0.65
.30 Rem. AR, Barnes 110 gr. TAC-X, 2880 fps 14 0.55
.243 Winchester, Barnes 85 gr. Tipped Triple Shock, 2900 fps 11 0.47
.30-30 Win., 170 gr. Nosler Partition, 2165 fps 10.25 0.63
