You really have to try different loads/bullets in your gun use what you get here as a guide. For instance my moose load is what my buddy shoots out of his Tikka but he uses Nosler partitions, it works well for him. I tried the partitions in my gun and got 1.5 -2" groups, just by switching to the corelocks my groups shrunk to 0.5-0.8" You got to try to find a load that your rifle likes thats the fun.
