Specifically, in traditional leveraction rifles, in most rifle chamberings, use of the right pistol primer routinely results in a significant improvement in ballistic uniformity and accuracy and it dramatically reduces the risk of a misfire.
In order to deliver maximum shot-to-shot ballistic uniformity when using rifle primers, it is necessary to deliver more striker energy than these guns can deliver.
Magnum primers are sometimes appropriate for hunts in very cold temperatures or with spherical powders if a load's ballistic uniformity (SD) is a little high.
Samples of each day's production are also shot to verify pressure, velocity and ballistic uniformity.
I started scientifically testing load variables 40 years ago, and started checking ballistic uniformity of carefully assembled handloads 30 years ago.
The loads shown in the accompanying chart were consistently accurate and demonstrated good ballistic uniformity.
This provides good load density--an important factor in ballistic uniformity and accuracy.
In the interests of gear and ballistic uniformity, our class--comprised of assorted gunwriting and magazine types--was issued 22-inch barreled Ruger American bolt actions in .
