Hmmm, interesting. I wonder what the results would look like if one measured the wound channel volume of ballistic gel using the same test. I also wonder what the results would look like if you shot 100 moose with each bullet.

I'm not saying that the .30-06 will always give a larger wound channel volume. It's certainly not an absolute, but my guess would be that the .308 would edge out the 6.5 bullet on average.
