I was one of the first guys on my block to get a 6.5CM. A Bergara. Really nice. It seemed all the rage to reload this with Berger's 140 or Hornady ELD's 140. Then a lot of life happened. Retirement, Moving, Building a new home. Just recently getting caught back up with the shooting world. Not that I know but it seems like the new kid on the block is now a 143. I don't think that was even an option some three years ago. There's a retired guy who used to be on this site a bit. Awesome military pedigree. Had an AI and reloaded a lot. I copied his posted recipes and was just getting my own twist on things when it all changed. Anyway, What's the difference? And am I right in that the 143 is the new king?
