I just develop the best loads possible without preconceived goals, as a simple change in bullet or powder batch can change everything.
That is why we try combinations in the first place, to allow the rifle to tell you what it prefers.
Had a .338 Mark V that shot 2-6 inch groups at 50 yards no matter what was loaded. After trying a dozen or more bullets and loads I pulled the damn thing apart and rechecked everything, including the mounts, bases and scope, to find a very slight contact point on the forend of the stock. Opening it up and floating the barrel dropped the loads under and inch at 50 yards so now I can take it out to longer ranges and fine tune the seating depth for best results.
So far the best 2 bullets are 225gn Hornady and 250gn Partition which isn't a bad combination for the .338 caliber anyway.
