The new cartridge is no better than the one you have except on paper. Game animals could give a scheit less about ballistics tables. If the one you own is a known shooter and you have dies, good data and components for it, Just shoot the barrel off it and quit worrying about the grass on the other side of the fence.
It’s not better, so that’s why I was contemplating just shooting the 6.5 CM until it needed a new barrel. I’m somewhat motivated by the amount of 7mm bullets and brass that I have.
