JB - thanks sir for the info.
DD - I see your logic wanting 'secondary shrapnel' but also wonder when it sheds mass how might that affect total penetration and if that's desired.
No doubt, many variations of how different bullets act and kill. Some 'energy dump' all internally, others 'exit leaving a good blood trail' where desired, etc. etc.
I do suppose if a typical mono kept 100% and missed a good vital pass thru - shrapnel might increase collateral damage and put the odds in favor of a quicker kill.
