You don't need a chronograph to see which will have better ballistics.
Since you have both, take them to the range. Set up a target at 50 yards, 100 and 150 yards. Sight in both to the same point of impact at 50. Shoot both at the 100 and 150 yard targets. The one with the least drop at both 100 and 150 is the better set up for longer range. Provided that group size is good enough for your purpose.
Several factors determine the trajectory of a bullet. Velocity is a big factor but scope hight from center of the bore can have a big part as well. The only way to know for sure is to shoot both and see.
You can't fix stupid....however ignorance can be cured through education!
