Hi AlWhy do you consider hollow points misplaced technology? Is this for all hollow points, or just in certain calibres? I am curious, as all the deer that I have shot with hollow points have dropped.
Also, there is no need to cast soft bullets smaller. The obturation just won't happen if the bullet is already groove diameter, which is a good thing.
I personally wouldn't go with a hollow point in 500 grain, but I am quite happy with my hollow point in 405 grain. The real issue is whether or not it has a flat nose, or rounded. A round nose hard cast bullet won't produce the same effect as a flat nose hard cast, and almost the same would apply with soft cast bullets.
As for leading, it all depends how fast you are trying to push your bullets. The original poster never talked about that.
