Blah!!!
There are different performances for each bullet at different ranges. Hard stop.
A Berger hunting VLD is different for each caliber and velocity range. A newer 7mm Hunting VLD is the only Berger bullet that I have used that didn't perform as advertised. It peciled through the ribs at 350 yards , which resulted in a slow deaths (luckily she stood in her tracks and fell over ~3 minutes after she was hit). so she was easy to find.
I've killed many elk (15 or so) with 7mm 168 VLDs and 180 Hybrids and all were perfect kills.
I will admit that 180 Hybrid targets are soft so they work best when velocities are below 2,500fps or less. They work great at long range.
