I was playing around with the JBS Program with 7mmRemMag 175gr Accubond LR bullets in mind, and it brought me to the question of, "What is the difference between G1 and G7?
For example using said bullet at 3,000fps, I entered the BC value of .681 G1 and then the .326 G7 value, and I found that the difference between the 2 values at 1,000 yards is only 1 inch. Even at 1,500 yards it's only a 2 inch difference.
Even Nosler states, "For the upmost accuracy, we recommend using the G7 value."
From what I understand, G7 was created with boat-tails in mind and G1 for flat base bullets BUT for a difference of 2" at 1,500 yards I don't see how it means anything.
Am I missing something here??
