300 WIN. MAG. HPBT 190 gr (Rifle ammunition Target (Match))

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 4638 J (3421 ft·lb) is computed from the bullet weight and muzzle velocity above, not quoted from the catalogue. Sectional density 0.286 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 0.267 is higher than 123 of them.
