Berger threads crop up here every few months and the gist of the comments can be boiled down to:

(a) I haven't actually used them but they aren't worth a damn--they blow up, don't penetrate, they don't leave an exit wound, and (with the exception of szihn) I know this for a fact because someone told me so.

or

(b) I have used them and they worked for me.
