In it's time, corelokt was considered the top brand for controlled expansion. They are accurate and will still give good controlled expansion. They will kill a deer. They don't cost $50 a box. What is wrong with that?
Use any of the major brands in their basic configurations, in 30-06 on deer, and you will kill every one that you hit in the heart lung area, probably with only a single shot.
nearly a century of research has gone into making sure that the market leader 30-06 ammunition will kill a dear in the 1-200 yard range, and any failure is going to have been a matter of chance, and not a flaw in the ammunition design.
Try not to get too wrapped up in perfection, because it can't exist, and unless you have faith in yourself and your gear, well, you're ruining your hunt.
I remember when the Fail safe came out from winchester. Walmart got hold of millions of boxes of fail safe, and promoted the hell out of them here in the land of 80 pound whitetail. Is a belted magnum in fail safe proper for a deer the size of labrador? hardly, but for a few years, that was all you heard about. During those years, thousands of deer were turned into cheeseburgers with plane jane ammunition.
My neighbor took his 30-30 out, using cast lead 180 grain bullets that I had loaded for him, and brought home a deer.
