Spear Grand Slam bullets?

@Northview902 The Grand Slam isn't a bonded bullet.

I wrote an article about 30 years ago for Handloader Digest where I tested a pile of bullets for terminal performance, mostly with 30 caliber but also others. Photos of a few Grand Slams are attached as is the diagram from Speer regarding the Grand Slam. The bullets were tested at various velocities. the conclusion with the Grand Slams was that they were better than the standard cup & core bullets IF the velocity didn't exceed the bullets limits- which when exceeded resulted in core separation- however the separation was well after the bullet would have killed the animal if shot at any "normal" angle. These were the original edition of Grand Slams.

Let’s not get into a pissing match over terminology. Speer called them a molecular bonded or some such decades ago and still do. I’ve never seen one separate and my experience is that they tend to pass on through.
However-the op chose to go in a different direction so it doesn’t seem important anymore anyway.
The fusion bullet has also been excellent the couple of times my daughter has used that one. . .

The fusion is an interesting Bullet as the jacket is electroplated to core. Speer Gold Dots are made the same way. That’s why the jackets aren’t as shiny as those made with separate jackets.
The hot core process has been long debated as to weather or not it is true bonding. I consider it in between. I shoot a lot of hot cores and grand slams.
