I recently posted the blurb for Evan Marshalls book on stopping power as something people could look at in deciding what ammunition to chose. Someone said he was 'discredited'. I've only read his first book (there are now three) so don't remotely consider myself qualified to say which is correct. Therefore I'm posting (with permission) from Mr Marshalls site. There are more essays there from 'third parties' in the 'commentary' section.
As a pure layman a few things are noticeable in this debate. If, as is often suggested, Mr Marshall is being sponsored to favour a particular ammunition or is biased in favour of a particular calibre. Then he's not doing a very good job of favouring them. Different calibres and manufacturers all do well. The criticism I have read of him was lightweight and not backed by any evidence. After dismissing his findings, the writers then usually go on to recommend their favourite calibre based on anecdotal evidence.
BUT I'm in the UK and haven't seen a gun magazine in a decade. Maybe things have changed.
So here are his articles from his web site.
