Out of only 2 animals, I still felt the Hornady 129sp was a slow killer...from a .260 Remington. The 6.5/284 was like Lightning with both the Nosler 120BT and 125 Partition. I tend to lean hard on the '06 sized cases. If I had a Creedmoor, I would start with those 2 and add the Barnes 120TTSX for real penetration. I know nothing of Scenars. So, of those 2 for the OP? Nosler. I "might" use the 140 PT in the Swede, but the Barnes 120TTSX most likely. Out to 300yds and a bit beyond, I just don't see a need for anything over 120-130 in any "standard" 6.5. In a 264WM. 140s make more sense, and tougher ones at that. I can't think of anything but Barnes for the 6.5/300Wby, ha
Odd that you think that the 129 is a slow killer. I have pretty much lost track of how many deer that I have killed with that bullet in my.260s at 2950-to just over 3000 fps. I have never had any complaints with the end result. I have used them out as far as 430 yards. I have shot them on my 530-yard range and less than moa accuracy at that range. They are my go-to in my .260s and I use the heavier bullets in my Creeds.
