Have used Rem Green Box in a 30-06, 180 grain for 30+ years with pretty good success on mule deer, antelope, and elk. Also reloaded the core-lokt for years. Probably 40+ animals taken with them. I can only remember one time that they failed. I took a frontal chest shot on a whitetail doe and the bullet did not penetrate, probably glanced off.. Lots of blood but the deer was never recovered. The Core-Lokts always shot so accurately in two Remington 700's.
Now I load the Remington Ultra Bonded Core-Lokt in 180 grain and get similar accuracy as I did with the Green Box. Several elk and deer have been taken with this round and the bullet performs well.
PS - Also really like the Nosler Partition in my 7-08, just not quite as accurate for me.
