Thanks for the explaination, BC.
I got curious, and decided to check out the Federal catalogue/calculator to compare their match rounds to their hunting rounds. Since this is federal's advertising, I hope they measured the BC the same way. It doesn't matter if the claims are inflated, as long as they were measured the same.
First off, I was wrong about the accubond and 308, I don't think anyone loads that. Here's some 30-06 figures first.
30-06 Springfield, 168 grain Gold Medal match.
Velocity:2700
ME: 2720
BC: .463
Drop at 1,000 Yards: -398.1
Drift at 1000 Yards in 10 MPH crosswind: 105.2
30-06 Springfield, 180 grain Nosler Accubond
Velocity: 2700
ME: 2914
BC: .518
Drop at 1,000 Yards: -366.0
Drift at 1000 Yards in 10 MPH crosswind: 90.3
Bear in mind, thats not a fair comparison because of the weight difference of the ammo...The deck is stacked in favor of the hunting round from the word go. Still though, thats great ballistics. It beats the 175 grain .308 GMM load by a good margin too.
The conditions for both rounds are a 24 inch barrel, 10 mph crosswind, zeroed at 100 yards, altitude 0 feet, temperature of 59 degrees F
