Is there one bullet that does it all in the grendel?

[Double Naught Spy]

There is no one bullet to do it all because bullet performance varies. By that I mean you have non-expanding, expanding softpoint, expanding petal, and frangible bullets (and maybe a couple more types depending on how you categorize). So do you care what happens to the bullet in the body?

People mentioned SST 123. It is one of my favorites as a workhorse bullet, but it tends to come apart, more like a frangible at higher velocity impacts and more like a softpoint at lower velocity impacts.

I am a huge fan of Speer TNT 90 gr. bullets. They are 100% frangible and I rarely find anything over 20 gr. in weight and that would be the bottom of the base and usually that is it. This work for varmints to hogs (up to 330 lbs so far).

I have killed more hogs with SST 123s and TNT 90s than anything else. I would not consider either to be fur friendly on smaller game such as coyotes or bobcats, in case you are after hides.
