Quite candidly, the only bullet test I ever put any faith in is the dead-animal test.
When it comes to the Hornady Interlock, and the Speer Hot Core and Grand Slam bullets, I've mixed results. Accuracy has often been incredibly good. Terminal performance has NOT always been so good, and I've had a number of these bullets, including the Grand Slam, come apart on game, limiting penetration.
So fundamentally I don't use any of these bullets for hunting anymore, even for deer. My basic all-around bullet is the Nosler Partition. It kills deer just as well as the other bullets do, and on bigger, tougher animals it works much more reliably in my experience, plus in most rifles it shoot very, very well in its own right.
I have plenty of reasons to stick with the Partition as well as other premium bullets that equal of even exceed its performance, and fewer and fewer reasons to run with Hot Cores, Interlocks, Game Kings, etc.........
