What do youse think?
I was unable to find anything on this in a brief search on the internet, but I remember reading somewhere that if you used a gun in a self defense scenario, you should have x amount of ammo of the same lot # to be used by Police for ballistics testing after the fact. I think it may have been Masaad Ayoob that said this (and excuse the rusty memory.) I know most frangible ammo is sold in lots of 6 - and tends to be quite pricey. Just another factor to bear in mind.
