"It might cause you more trouble in court and using what the police use is very good advice. "
Hear, hear! Very good advice. If you actually kill someone with a handload of razor flechettes or a commercial round named "Terminator", the cops will probably let you go.
But, any time for the next seven or eight years, the wife, girlfreind, kids, or bookie of the dead burglar can sue you in civil court for wrongful death, loss of companionship, hardship, and lots of things only a lawyer can dream up.
You will be on the stand years after the event explaining to a scowling civil jury just why you loaded up your Mossberg 590 ASSAULT WEAPON with nine rounds named "PerpShredder II".
Standard, OTC hunting rounds are better from a legal defense standpoint.
For those of you on a budget, I recommend the Remington 870 Express. I have 2 of em', a 12 ga and a 20. It is IMHO, the best deal for the value conscious consumer. Game loads are also a good value and you will probably achieve your objective even if your aim is off.
However, the best advice has already been given, call 911, try to get out of the house, let the police do the shooting.
Doesn't matter if it's PerpShred or 00 buck. It's better to be tried by 12, than carried by 6! Still in civil litigation from an 1998 "ON DUTY" fatality shooting with Sheriff's Department issue 00 buck. I live in an apartment with nothing but sheetrock seperating the rooms. I want something that will not cause an innocent to become a victim. If anyone is involved in a shooting of any kind, be ready for civil litiagtion. It's a lawyer's world out there.
