The higher the impact speed of C&C bullets, the less predictable their terminal performance tends to be. Which is why heavy, high-SD C&C bullets launched from standard-velocity cartridges tend to work quite well. I try to stick with a sub-3000 fps launch speed, but 2700-2800 fps may be even better for C&C terminal repeatability. With monos, it seems to be the opposite.
I agree with that notion also. Even moderate-weight cup/cores at 2800 or less are generally great killers and don't tend to want to come completely apart on game. They can be fantastic killers at high velocity too, but things start to be far less predictable with regards to penetration and overall performance. If you ask the average hunter around here about day-in, day-out, reliable performance over the decades, most will likely point to the boring old 308 and 30-06 with cup/cores at standard velocities. When we start adding case capacity, bullet construction becomes more of a topic.
