What is Necksplitting?
Necksplitting is the outcome of over-stretched or resizing of the cartridge. Necksplitting is most common when the cartridge is excessively resized. Necksplittting can be seen as a crack in the cartridge.
Why Do Case Necks Crack on Polymer Cased Ammunition?
True Velocity ammunition is made with carefully engineered polymers. Damage to the polymer may occur during firing if the polymer is required to stretch farther than intended before it receives support from the chamber walls.
How to Solve the Recurring Necksplitting of Polymer Cased Ammunition
Consult a qualified gunsmith to inspect the chamber of your firearm. The gunsmith should ensure that the chamber of your firearm is in compliance with the Sporting Arms and Ammunition Manufacturers’ Institute’s (SAAMI) specifications for the specific caliber or round. Keep in mind that most protocols for checking chambers include an assessment of chamber diameter. Just like brass, if the chamber is too large in diameter, splitting can occur in the cartridge.

Another possibility of why neck splitting is occurring could even be caused by improper annealing from the factory. All brass is annealed and is usually polished afterward.
How to Solve the Recurring Necksplitting of Brass Cased Ammunition
