Building a 7mm PRC on a MacBros Evo II. Light weigh is paramount. Which bottom metal do we like---Hawkins DBM or Hawkins Oberndorf. The Oby is lighter and I am a traditionali

I've used the Hawkins Oberndorf on 2 lightweight short action builds and really like the fit and finish of them. And they seem to work just fine and price isn't terrible for what you get.

You could ask the Mack Brothers.

I think you've answered your own question but I do like the Hunter DBM
