I wonder what is all this new bullets and new scientific technology that the experts keep ranting and raving about. There have always been all kinds of bullet shapes ( round nose, flat nose, hollow points, etc.). Soft lead deforms easier than hard lead and that has always been fact.
The new technology and scientific break through is nothing but good advertising.
The FBI does a lot of changing guns and bullets and that leads me to believe they don't know what is best or what they want. Larry
