The difference between G1 BC and G7 BC is that the G7 BC is more representative of modern long-range bullets. The G1 BC has traditionally been the ‘standard projectile’ used to define BCs for the entire sporting arms industry. The problem herein lies that Berger Bullets aren’t standard projectiles. Berger Bullets are modern long-range bullets capable of extreme precision. The standard G7 projectile has a long boat tail and pointed ogive as compared to the old G1 projectile which has a short nose, flat base and bears more resemblance to a pistol bullet than to a modern high velocity long range rifle bullet.
