You are right Swampman, a Core-Lokt is a great deer bullet. My brother shoots the 140's in his 7mm-08 and won't shoot anything else. I sure wish Remington would load the 120's in the .260 as I think that would be a grand bullet for deer.
Remington does or did load a 120 in the 260. It wasn't a core-lokt.
In my 260's it wasn't as accurate as the Federal 120.
I like the 120NBT and it puts them on the ground in short order.
