Discreet Ballistics has been working on projectile design for nearly a decade. In that time we've had ample opportunity to determine what does and doesn't work in the field.
We specialize in solid copper projectiles which are about 25% longer than traditional lead core pills of the same weight. Not only do longer projectiles typically require faster twist rates to properly stabilize, they also require more time to produce with precision.
Presently, all of our solid copper subsonic expanders are made one by one on CNC lathes. We try to strike a good balance between keeping the projectiles within tight tolerances (conformation to the print) and cycle time (how quickly they can be made within the tolerance). A longer and heavier bullet will necessarily require more cycle time to maintain sufficient levels of precision. The precision we maintain is part of what makes our projectiles among the most accurate subsonics available.
Experimenting with longer and heavier projectiles in the past has led us to the conclusion that the juice is not worth the squeeze. Sure, there may be instances where the added pe*******on of a heavier projectile is beneficial, but for nearly all big game in this western hemisphere, we've found it to be unnecessary. Our 280gr 8.6BLK has taken the largest of them including: moose, elk, eland, you name it. Of the hundreds of post mortems observed, pe*******on with our 280gr expander has never shown to be an issue.
Some guys will always prefer the Hellcat. But our 280gr Selous customers choose the Z06. It beats the Hellcat around a track all day, every day - with precision.
