It's been talked about before many times, but as has been stated, they usually are hard to eject, and aren't that accurate in Handis. Not to mention that they are usualyl very dirty. The best I remembering me getting was from 55gr HP at 1 1/2" smallest from a bench.
As Stimply said though, if you want cheap plinking and you don't reload, then there are some fun to be had. I'd rather save myself the time from cleaning up from them, and be reloading with the bullet of my choice. You got to love the hobby
