At 50 yards, most of your bullets are on the way UP from the bore to the line of sight, so almost every one will be at a similar elevation. As you get farther out, the bullets will begin to show their differences in velocity, ballistic coefficient, and point of impact in a significant way. If you could shoot your groups at the farthest range you would be hunting, THEN you can determine which loading will work best from your rifle. If your average shot is only 50 yards, the choice between those 4 could be based on lowest price and highest availability. Good luck on your futher testing.
