I am currently reloading Nosler Partition 170-grainers for my 30-30.
I love the partition's mix of great expansion and lots of penetration.

I really think it's a great choice, as long as the particular 30-30 groups them well.

That having been said, I also strongly agree that just about all the current market offerings for 30-30 are extremely adequate for deer and black bear, and wouldn't disappoint.
