i'm almost done with a similar build. 28" lothar walther .260 barrel built off of a 110 300wm in a boyds pro varmint with PTG DBM. just need to pillar and bed it then take it out. I wanted the long action to be able to seat the vld's way out there. hoping for 3000 ft/sec with 140's using RL26 should be a huge improvement over my .308
