I have tried the 142 NABLR in probably 15 different 6.5s. From the 6.5 CM, .260 Rem, 6.5SLR, 6.5x55, 6.5-.284 Norma, 6.5SS, 6.5 SAUM, 6.5-06AI, and .264WM. Nothing has shot them what I would consider well. I now use the remaining box for fire forming brass. That is about all they are good for in my opinion.
We have used 140 HVLDs for numerous game animals. From coyotes to big mulies. Plenty of guys I know have used them on elk and black bear too.
The 140 NAB would be my 2nd choice. They always shoot well.
The 143 ELD-X are good, as long as you can get them to shoot. I am only about 33% on them for rifles that shoot them amazingly. The other 67% were just OK.
