Thanks for the kind words guy!
With that setup you can go with either our Oberndorf or the M5 Oberndorf. Both have options for the extended Wyatt boxes. Our Oberndorf bottom metal is about 2oz lighter, but it's not as modular as our M5 Oberndorf, which is cut for M5 inlets. The M5 Oberndorf has a little thicker floorplate to help relieve follow spring pressure for larger cases like 300RUM for better feeding.
Let me know if you have any questions.
Thanks for the great explanation. I will definitely consider an M5 Oberndorf BDL style for my next build. Gives multiple options. Great idea!
