Am I correct to assume that because you have seen over 100 Barnes DRT kills (and I am not saying that you have not) someone else has not experienced substandard performance from them?
I on the other hand have never seen a Nosler hornady Scirocco and grand slam failure.
Either way like I said failures are not written in stone, and they do not happen often but when talking specifically about expansion I have seen only barnes, A few but only Barnes.
