Re: Do JLK Bullets Really have a BC that is So Much Higher than Berger ?
I believe it's how BC is currently reported by Berger.
They've normalized their G1BCs to provide an average from muzzle to target.
For most it accounts for the variance of G1BCs as velocities change in flight.
JLK BCs are still based on some muzzle velocity, like all other bullet makers.
This can benefit or hurt you, depending on your ballistic software.
Most software does not adjust BC incrementally with each incremental velocity downrange. This is in a sense a circular loop, in that BC affects downrange velocity, which affects BC!
But this is possible, and so probable somewhere out there.
Berger normalized expected velocities with their bullets, and assigned BC based on that velocity, to reduce software prediction error across a gamut of ranges.
It's a good move.
Bergers and JLKs are actually pretty close, but I think Berger's BC numbers are more useful.
