Why should it matter?
Carry what works the best in your gun- don't base your decision on what
some PD does or does not do. I've -never- heard of this becoming a real
issue in a true SD case. Some people that huff too much ayoob fumes
may think it makes a difference but I've never seen any proof. I think even
ayoob has said that as long as the ammo is commercial and you have a lot
number/box it came in to back it up thats about all you really need.
Let's let this old wives tale/urban legend die a quick death, already.
