Bonded bullets

I don't see how that's physically possible, the exact opposite sounds more correct. Unless te 100 gr was going way way faster, a softer more
Expansive bullet will create a
Larger diameter wound canal, can't change the laws of physics

Granet, the copper bullet will penetrate further

Ya..... Not buying it. Their is no way an all copper 100gr bullet could have a bigger wound channel than a 150gr Sierra, nosler or hornady. Unless you are talking about penetration depth and not wound channel diameter

Might help if one reads the referenced article. As it happens there is a lot of experimental evidence to show that the premium bullets perform better than classic bullets when the product of depth and diameter is considered.

The wisdom about how large that wound channel needs to be goes back to our Mesolithic (5,000 BC) ancestors and has continued through to today. Most of us didn't know that but a team of astute archeologists made the connections. The reference and discussion are in the Ideal Bullet Weight paper.
