All things being equal, I'm convinced cases with short, squatty powder columns have an inherent accuracy advantage that will show up consistently in apples/apples testing over a large sampling.
But I also doubt it means much for the majority of us hunters...
Exactly....that's why I think it's funny that hunters think it's important.
I'd spend a lot more time and money on the quality of the rifle and fixing accuracy-robbing problems rather than vague, obscure stuff.
