[quote="thebrassnuckles"]ok, what bullet would be the most frangible?

The trend is to use the different Sinter Metal Bullets, but there is a far cheaper and effective set of bullets, "For Us". Consider, the .451 ACP expandable hollow points, that start life in the 900fps range, they are still expanding at 300fps. Now move them at any speed above 2000fps and typically 2500fps++ for us, what will be the results? They self destruct into thousands of little flat flecks, with 5-6 curly-cued, like a pigs tail, shards, about the size of a pencil lead thick and way less than a half inch long (which might scratch you, but little more and are not considered dangerous at all by themselves)..
These hyper expanded bullets wont normally penetrate an interior wall, except on rare occasions and then with very minimal terminal results, as in nearly none. Sure don't want to kill the neighbor's dog, so these are pretty darn good in selected environments!
Any of the Hollow points made for the 45 ACP or 45 Colt are your best bet. I religiously use the 230 grainers, and love the 185's as well, for home defense or when the amply and vociferously dangerous red squirrels are threatening an attack..wink
