Question is... which cartridge to use. I’m leaning towards a 6.5, but my 270 WSM and 270 Roy are sick accurate.

Options are 80 grain TTSX 257 Roy, 143 ELDX 6.5 CM, 130 ELDM 260, 143 ELDX 6.5 PRC, 130 VLD 270 Win, 130 AB 270 WSM and 150 ABLR 270 Roy.

All are 1/2” or smaller shooters. 270 Roy is the heaviest 8.5#; Lightest 6.5 CM/260 around 6.4#.

Which one would you choose and why?

Thanks for your opinions.
