[QUOTE="FEENIX, post: 1217841, member: 14204"] Barnes show their BC as G1 while Hammer Bullets is G7. G1 and G7 are not the same, G7 is the lower of the two; it's the updated equation and the better system of measuring the BC. G7 provides more accurate and reliable results when calculating trajectory using ballistics program that allows for a G7 to be used. Below is just an example for comparison ... Barnes 168 TTSX, G1=.470; G7=.xxx Hammer Bullet 166. G1=.xxx; G7=.227 Berger 168 VLD. G1=.497; G7=.255 [/QUOTE]
