This video from Brownells Gun Techs Caleb Savant and Steve Ostrem explores the interchangeability of rifle and pistol primers in reloading. They explain the fundamental differences in primer cup thickness and sensitivity between large pistol, small pistol, large rifle, and small rifle primers. The video highlights that while some handgun cartridges can use small rifle primers (like .454 Casull and .38 Super) due to their higher pressure requirements and the rifle primer's thicker cup, it's crucial to reduce and carefully work up loads to avoid exceeding pressure limits. Conversely, pistol primers are not robust enough for rifle cartridges. The experts strongly advise adhering to reloading manual specifications or conducting thorough research with credible sources before attempting any primer substitutions, emphasizing the risks of potential malfunctions and safety issues.
This video investigates hang fire issues experienced with VihtaVuori N550 powder in 6.5 Creedmoor. The content focuses on testing 8 different small rifle primers and 2 large rifle primers to identify which combinations contribute to or mitigate the problem. The goal is to diagnose and potentially resolve the unreliable ignition. The description also notes an update regarding the removal of links to comply with YouTube policies.
