2000 mr--one of my favorites, great for 224 valkyrie as well (surprised you haven't dabbled in one of those yet).
im toying with ideas for a bolt rifle
6.5 cm 6.5-06 nexto a 30-06
i have a ton of 30-06 brass and also 300 weatherby mag i can convert to 6.5-06 or 6.5-300wm im leaning twards building a 6.5-300wm bolt gun over the 6.5-06 though i just didnt have the dies to convert the weatherby brass on hand atm
