Reading these numbers

Both a G1 and a G7 ballistic coefficient are published for this bullet. BallisticApp defaults to G7, because the G7 standard projectile is shaped like a modern boat-tail bullet and holds its coefficient far more steadily across the transonic range than G1 does.

Muzzle energy of 4115 J (3035 ft·lb) is computed from the bullet weight and muzzle velocity above, not quoted from the catalogue. Sectional density 0.271 describes weight per unit of frontal area; divided by the ballistic coefficient it gives the form factor, which is how much drag the shape adds over the standard projectile.

Among the 488 loads of this bore diameter in the database, this one's G7 BC of 0.308 is higher than 192 of them.

These figures are the bullet's starting point. What you actually dial depends on your rifle's zero, the air you're shooting in and the wind on the day — BallisticApp solves that on the phone, offline, using the same G1/G7 tables and this database.
