If ammo didn't matter why did the whole "Black Talon" and "Cop killer" episodes happen in the first place?
Blissninny gun banner got their collective soiled panties in a knot over the name and found a good 'evil' name they could pounce on. Winchester simply changed the name of Black talons to Rangers and still sells them. There are even better bullets out there now than the Black Talons.
Once again, RA, can you point to a case where handloaded ammunition led to a conviction of a shooter where factory ammunition might not have?
Didn't think so.
