Recently a discussion came up around rifle calibers, specifically "precision" calibers.
Specific to terminal ballistics, is there much consideration between a 6.5 or .308 offering? Or are the reasons for one over the other minimal or focused on different factors?
I know there is a tonnnnnn of info out there but I've had trouble digesting it. Especially given what appears to be fanboyism surrounding 6.5 and nostalgia for .308, but that could just be a bias on my part.
What's up with these two?
