one pretty relevant observation here, might be that tiny bits of lead, can and do, loose themselves from the remainder of the bullet (more so on common C&C bullets), and might very well end up in meat.
a shoulder shot is logically tougher on a bullet than water, and more likely to cause tiny lead fragments to come off the main projectile.
when we say "XXXX bullet had YYYY penetration and retained 65% of its original weight", that OTHER 35% went somewhere, yes?
Maybe CH's testing efforts highlight where some of that other 35% goes.
I've not had consistently stellar results with Barnes bullets (copper fouling, less than stellar accuracy, high source costs) but this does make me reconsider a bit.
As for wounded game commentary from the critics...... I cant cast any stones, having lost a couple deer due to poor shot placement.
I'm impressed that's never happened to BWalker, apparently. Good on you, sir. May you retain that trend.
