I recently bought this M77 from the used gun rack at Cabelas. Cal. 30 06,
serial number 70 - 98559. For use as a back up rifle on elk hunts. Looking for an accurate load using a 180 grain bullet, and 4831, 4064, ..
Sam, my favorite load for the M77 30.06 is 51.5 Grs of IMR 4350 with a Nosler Partition Bullet, I went to the range yesterday and it shot sub minute of angle groups.... RR
4064 and 4350 are both good choices with the 30/06 & 150 grain bullets. 4064 is a little more economical, showing 7 grains less powder in Sierra No. 5 for top velocity around 3000.
I've never been let down in the accuracy department with IMR 4350.
