gwp4ever,the only thing worse than having a bullet getting hung up in some turds sweatshirt is a bullet going through that turd and hitting a family member.I held up my end of the deal I used a pair of levi's that for some reason shrunk,and I was keeping them just in case my butt shrunk,well the pants are only 1/2 worn,mostly in the knee from looking under cars and trucks.The frangibles are jacketed but is filled with a metal that looks like pwuter,the jacket stayed intact.I doubled the jeans so the bullet would go through 2 legs of denium.No problem.went through and into the backstop.It left only a small hole in both legs.Next I put an old army jacket(it shrunk also)behind the jeans.The bullet went through the jeans like before but started coming apart going through a jacket liner and jacket.I doubled the jacket and shot again,this time the bullet came apart but had enough force to tear the rear of the jacket to shreds.I would give anything not to be behind that bullet when It comes apart,it's like small buckshot.I used extreme ballistic shock ammo.The pmc is not in stores now that I visit so I could not try them.But recaping the event,the bullet will go through 2pairs of jeans without coming apart,it started to come apart a little with a military liner and jacket,with the jacket doubled the bullet went through jeans,liner and rear of jacket before severe signs of breaking up,but the jacket and small bits of pwuter can't be found.If your intruder is dresses in 2 pairs of jeans,2 military jackets and liners,he still may be severely injured,I don't know about that.But if he is only clad with a shirt and 1 pair of jeans I would not hesitate to use the 9mm with extreme shock anti personel rounds.They are spendy,and I have ruined a pair of jeans and an old tattered military jacket with a military liner.Some home less guy hates us right now but I got to see the damage.The bullets run about 3 dollars each.1 box of 20 for 46.00,I have seen them in sportsman guide for alot less,but they are still expensive.Drop-Shot
