Drag function is the efficiency of the body design. All bullets slow down, but some of the same weight and diameter slow down faster than others.
G-1 is for flat based bullets and those with teeny weeny boat tails like the .224 Sierra 52 Matchking - it flies like a flat base.
Flat base and little boat tail bullets are classed as G-1. Bullets that are loooong and have loooong boat tails, are classed as G-7, and have a different numbering system for the BC, and different math to calculate their path through the air.
A G-7 BC of 0.190 is a MUCH HIGHER BC than a G-1 BC of 0.275.
In .224" diameter bullets, G-7 bullets at ~68 grains - the Hornady 68gr match is a G-7, as is the 69gr SMK , and 70gr. Burger.
