Edgequello. You are absolulely right.If they had hung the word Magnum on the end of the 45-70, then it would be up to the task. The truth is that nothing is going to still be standing after a GOOD hit from a 405 grain bullet at around 1900fps. It matters not what the bullet is fired from. I believe the wound channels were also larger than those delievered by larger guns when they tested in that area. I would have to read the article again. But your main point is so often overlooked. Its the bullet that does the work, not what its fired from. You can't ask much more of a bullet than to shoot through two Cape buffalo. Not only will it penetrate but it created a very large wound channel.
