I have used Reemington Cor Lokts in lots of chamberings. I have used them in .243, .308 Win and .30-06 enough to have an opinion as follows:
My favorite: .243 Winchester - 100 grain - The whole family used this load for deer until they became unavailable. Now it is I/L BT's or NPT's. We never had any issues with performance and still haven't. REL-19 gives the best accuracy for us.
My second: .308 Winchester 150 grain - We used this in factory and handloads. Switched to 150 gr I/L (availability) Good for deer, I prefer Power Points or NPT's for elk.
My third: .30-06 Springfield 180 gr PSP. I used this for many years in handloads and factory when needed. Unfortunately, about 15 years ago I started to get erratic performance. I still have some factory around but no longer handload it. I use Interlocks now for practice and fooling around. I use a handloaded NPT for most hunting.
