I have used the Nosler Solid Base in the past in both 30'06 and 7mm Rem Mag. although I loaded them myself. I am sure glad Nosler reintroduced the solid base, although I regret I have not the room to reload, as I used to.
I also have purchased some of the newly factory loaded Federal Premium Nosler Solid Base...they are VERY accurate in my Ruger M77 7mag, especially for the money!
For small whitetail through large black bear, I trust them...As you said, Partitions are first choice for Elk but the Nosler Solid Base will do it to it as long as you put it where it belongs. But, that goes without saying. :-)
Stay Safe. Happy Hunting/Shooting.
