Manufacturers have adopted "standard" ignition systems to sporting cartridges not because of superiority but simply because of affordability. This is a matter of scale, as the size of the cartridge increases, the additional cost of these priming systems diminishes, as a function of total cost, until the ballistic advantage becomes worthwhile.
Background & Definitions
has been discussed in previous articles by both this author and Byrom Smalley, particularly those works pertaining to the short-fat case concept, ideally, to maximize both cartridge performance and ballistic uniformity, several primer blast (or plume) related factors are critical. With this in mind, the ideal primer blast would:
