OK, the first bullet, the BAR TSX FB is a Barnes lead free bullet. Here is a link to the bullet on Midway

The second bullet is most probably a Speer 55 grain spitzer point. Here is a link to Midway for the bullet I am referring to.

If loading a lead free bullet, I would go with the Barnes data set. If your FMJ bullets have a lead core, go with the Speer dataset.
If you start with minimum loads, either datasets would work. If you are loading for the AR platform and 5.56 x 45, any 223 data should be safe, because the gun is good for 60,000+ psi loads of 5.56 ammo.
