If you read the original post, the person DOES NOT reload and implies that his friend has limtied or no handgun hunting experiance. So yes, shooting a more popular round would have advantages.

I like to hunt with things other than the top sellers too and there is nothing wrong with that. I don't get the concept behind a lot different rounds, the 7-30 is just one of them. I'm not saying it doesn't work. However, there are situations when using something more mainstream is a better choice.
