Here is a link to a write up that I did from our trip to Africa a month ago. It is about half of the story, I just have not had time to finish the story. There were 37 plains game animals taken with various cartridges and bullets from 25cal to 37cal. The only animals that did not drop within 40y were animals hit with non vital shots. Here is the read:

The only thing I will say about the terminal performance is, keep the stability factor at 1.5sg or higher calculated at sea level and you will very happy. We have a lot of guys out there flattening pigs with small for caliber bullets and fantastic results. Over the last several years we have been responsible or with others on hundreds of big game animals taken with Hammers. Terminal performance is very good. Frankly if it were not exceptional we would not market them.
I try to stay out of these threads that I did not start as it is much better when others are giving experience. It is easy for the guy making and selling the product to give glowing reviews.
