A couple of loads that have worked well in my Ruger 77 are 42.5gr of Varget with either a AB, or BT 140gr Nosler. Either is just fine for deer/ Lopes. I usually do my load & practice with the BT, then hunt with the AB. The other load is 42.5gr of RL-15 with a 120gr Barnes. Either is sub MOA for me, usually around 3/4".
Have fun with whatever you try.
