I don't know enough about any of the bullets to make an informed opinion. I do know that I am looking for the bullet that knocks them down the fastest. If that is a newer bullet than whatever it is I am using, I will switch. I think the problem is, proving a new bullet is better.

For example, I use the Nosler Partition in my 30-06 and it has knocked down almost every deer I have put it into. The handful that ran haven't gotten out of sight. It would be hard for me to switch bullets with performance like that. But if someone can show me that another bullet will stop even more of them from running, then I would switch.

I don't have that same experience with blackpowder yet. The doe I shot several years back almost ran just out of sight but it was a pass through with good blood trail. The 4 ptr I shot last year got away with very little blood trail that quit after 100 yards. Apparently I didn't get a pass through. I was using a pack of Knight hollowpoint bullets. I switched to Hornady SST this year but haven't gotten to see how they perform on deer yet. If the Deep Curls are better, I would switch for sure.
