I bought a Ruger 77 .338 Win. Mag., 24" bbl., in 1974. I have killed four elk and one Mule deer with it. I used Norma MRP powder and the Hornady 225 grains Interlok on two elk and Norma MRP with the Nosler Partition 210 grains on two elk and one Mule deer.
They worked perfectly, except with a Nosler Partition 210 grains on one elk where I shot badly requiring a five hour tracking job to finally find and finish the job due to my poor shooting.
With those two loads I cooked up the Ruger would shoot 3/4" off the bench when I did my part. BTW, I had it Magna Ported not long after I bought it. Tamed the recoil a bit, seemed to me.
