Nice looking rig!
I started out with the same 30-378 Accumark. The only thing left from the original rifle is the action and the trigger. I sent it off to Gordy Gritters and he installed a 30" Krieger barrel, re-chambered it to a 30-378 Improved (Blown out 45 degree shoulders and less body taper – allows about 10% more powder), installed a Vais muzzle brake
, bedded it in a McMillan A-5 stock and dropped the trigger pull to 2 lb. Gordy also made me a set of custom dies using the reamer he cut the chamber with. I sent the stock to Danuser Machine shop and had them install their hydraulic recoil reduction system. I bedded a Near Mfg. 45 MOA rail to the receiver, and use a Near Mfg. Alpha ring system (one-piece mount) to cradle my Hensoldt 6-24x72 scope. I lost track of how much money I have wrapped up in this rifle...but it was worth it.
