Making no comment on the quality of the ammo, I would not use something called "Extreme Shock" ammunition. It seems to me a name like that could be an invitation to a murder indictment or at least a huge civil suit judgement if you were ever forced to defend yourself with a firearm.
"Your honor, Mr. Jones deliberately bought the most deadly, most damaging ammunition he could find planning in advance to kill, when he could have purchased far less dangerous bullets that would likely only caused minor wounds while still allowing him to defend himself."
I know, there are all kinds of holes in this argument, but would the judge and jury know?
The safest ammunition you can use from a legal standpoint is whatever ammo your local police department uses.
